React vs Vue vs Angular vs Svelte

In this article, I'm going to cover which of the top Javascript frontend frameworks: React, Vue, Angular, or Svelte is the best at certain factors and which one is the best for you. There are going to be 5 factors which we are going to look at: popularity, community/resources, performance, learning curve, and real-world examples. Before diving into any of these factors, let's take a look at what these frameworks are.

🔵 React

Cons:

• Small community
• Confusion in variable names and syntax

The 1st Factor: Popularity

All of these options are extremely popular and are used by loads of developers. I'm going to compare these 4 frameworks in google trends, NPM trends, and the Stackoverflow 2020 survey results to see which one is the most popular.

Note: Remember that popularity doesn't mean it has the largest community and resources.

Google Trends

Google trends measures the number of searches for a certain topic. Let's have a look at the results:

Note: React is blue, Angular is red, Svelte is gold, Vue is green.

The image above contains the trends for these 4 frontend frameworks over the past 5 years. As you can see, Angular and React are by far the most searched, with React being searched more than Angular. While Vue sits in the middle, Svelte is the clear least searched framework. Although Google Trends gives us the number of search results, it may be a bit deceiving so lets of on to NPM trends.

NPM Trends

NPM Trends is a tool created by John Potter, used to compare NPM packages popularity. This measures how many times a certain NPM package was downloaded.

As you can see, React is clearly the most popular in terms of NPM package downloads. Angular and Vue are very similar on the chart, with them going back and forth while Svelte sits at the bottom once again.

Stackoverflow 2020 Survey

In February of 2020, close to 65 thousand developers filled out the Stackoverflow survey. This survey is the best in terms of what the actual developer community uses, loves, dreads, and wants.

Above is the info for the most popular web frameworks. As you can see React and Angular are 2nd and 3rd but React still has a monumental lead. Vue sits happily in the middle but Svelte is nowhere to be seen.

Above are the results for the most loved web frameworks. As you can see, React is still 2nd and this time Vue sits in 3rd. Angular is in the middle of the bunch, but yet again Svelte is not there.

Note: Angular.js is not Angular

Above are the most dreaded web frameworks. As you can see React and Vue are towards the bottom (which is good) while Angular is one of the most dreaded web frameworks. This is because React and Vue developers tend to make fun of Angular, mostly because of its predecessor Angular.js. Svelte is not on this list which is good for the framework.

Explaining Svelte's "Bad" Results

Some may say that Svelte performed poorly compared to the other 3 frameworks in this category. You would be right. Svelte is the new kid on the block, not many people are using it or know about it. Think of React, Vue, or Angular in their early stages: that's what Svelte is currently. Most of these frontend frameworks comparisons are between React, Vue, or Angular but since I think that Svelte is promising, I wanted to include it in this comparison. Most of the other factors, Svelte is ranking quite highly in.

Wrapping up the 1st Factor: Popularity

From the three different trends/surveys, we can conclude that React is the most popular out of the three but with Vue and Angular just behind.

Popularity:

1. React
2. Angular
3. Vue
4. Svelte

Note: it was very hard to choose between Angular and Vue since they are very close together but I think Angular just edges out Vue in the present day.

The 2nd Factor: Community & Resources

This factor will be about which framework has the best community and resources. This is a crucial factor as this helps you learn the technology and get help when you are stuck. We are going to be looking at the courses available and the community size behind these frameworks. Let's jump right into it!

React

React has a massive amount of resources and community members behind it. Firstly, they have a Spectrum chat which usually has around 200 developers looking to help you online. Also, they have a massive amount of Stackoverflow developers looking to help you. There are 262,951 Stackoverflow questions on React, one of the most active Stackoverflow tags.

React also has a bunch of resources and tutorials. If you search up React tutorial there will be countless tutorials waiting for you.

Here are my recommended React tutorials for getting started:

Free: https://youtu.be/4UZrsTqkcW4
Paid: https://www.udemy.com/course/complete-react-developer-zero-to-mastery/

Vue

Vue also has loads of resources and a large community but not as large as React. Vue has a Gitter chat with over 19,000 members. In addition, they have a massive Stackoverflow community with 68,778 questions.

Where Vue really shines is its resources. Vue has more resources than I could imagine.

Here are my recommended Vue tutorials for getting started:

Free: https://youtu.be/e-E0UB-YDRk
Paid: https://www.udemy.com/course/vuejs-2-the-complete-guide/

Angular

Angular has a massive community. Their Gitter chat has over 22,489 people waiting to help you. Also, their Stackoverflow questions asked is over 238,506.

Like React and Vue, Angular has a massive amount of resources to help you learn the framework. A downfall to these resources is that most of them are outdated (1-2 years old) but you can still find some great tutorials.

Here are my recommended Angular tutorials for getting started:

Free: https://youtu.be/Fdf5aTYRW0E
Paid: https://www.udemy.com/course/the-complete-guide-to-angular-2/

Svelte

Svelte has a growing community yet still has many quality tutorials and resources. An awesome guide to Svelte and their community is here: https://svelte-community.netlify.app. They have a decent Stackoverflow community with over 1,300 questions asked. Also, they have an awesome Discord community with over 1,500 members online on average.

Svelte has a lot of great tutorials and resources, despite it only coming on to the world stage quite recently.

Here are my recommended Svelte tutorials for getting started:

Free: https://www.youtube.com/watch?v=zojEMeQGGHs&list=PL4cUxeGkcC9hlbrVO_2QFVqVPhlZmz7tO
Paid: https://www.udemy.com/course/sveltejs-the-complete-guide/

Wrapping up the 2nd Factor: Community & Resources

From just looking at the Stackoverflow community and the available resources, we can conclude that all of these 4 frameworks have a massive community and available resources.

Community & Resources:

1. React
2. Vue & Angular*
3. Svelte

*I really couldn't decide between the two!

The 3rd Factor: Performance

In this factor, I will be going over which of these frameworks are the most performant. There are going to be three main components to this factor: speed test, startup test, and the memory allocation test. I will be using this website to compare the speed of all frameworks.

Speed Test

This test will compare each of the frameworks in a set of tasks and find out the speed of which they complete them. Let's have a look at the results.

As you can see, just by the colours that Svelte and Vue are indeed the most performant in this category. This table has the name of the actions on one side and the results on the other. At the bottom of the table, we can see something called slowdown geometric mean. Slowdown geometric mean is an indicator of overall performance and speed by a framework. From this, we can conclude that this category ranking:

1. Vue - 1.17 slowdown geometric mean
2. Svelte - 1.19 slowdown geometric mean
3. React & Angular - 1.27 slowdown geometric mean

Startup Test

The startup test measures how long it takes for one of these frameworks to "startup". Let's see the table.

As you can see, Svelte is the clear winner. For every single one of these performance tests, Svelte is blazing fast (if you want to know how Svelte does this, move to the "Why is Svelte so performant?" section). From these results, we can create this category ranking.

1. Svelte
2. Vue
3. React
4. Angular

Memory Test

The memory test sees which framework takes up the least amount of memory for the same test. Let's jump into the results.

Similarly to the startup test, Svelte is clearly on top. Vue and React are quite similar while Angular (once again) is the least performant. From this, we can derive this category ranking.

1. Svelte
2. Vue
3. React
4. Angular

Why is Svelte so performant?

TL;DR:

• No Virtual DOM
• Compiled to just JS
• Small bundles

Before looking at why Svelte is how performant, we need to understand how Svelte works. Svelte is not compiled to JS, HTML, and CSS files. You might be thinking: what!? But that's right, instead of doing that it compiles highly optimized JS files. This means that the application needs no dependencies to start and it's blazing fast. This way no virtual DOM is needed. Your components are compiled to Javascript and the DOM doesn't need to update. Also, it also takes up little memory as it complies in highly optimized, small bundles of Javascript.

Wrapping up the 3rd Factor: Performance

Svelte made a huge push in this factor, blowing away the others! From the three categories, let's rank these frameworks in terms of performance.

1. Svelte
2. Vue
3. React
4. Angular

The 4th Factor: Learning Curve

In this factor, we will be looking at how long and how easy it is to be able to build real-world (frontend-only) applications. This is one of the most important factors if you are looking to get going with this framework quickly. Let's dive right into it.

React

React is super easy to learn. React almost takes no time to learn, I would even say if you are proficient at Javascript and HTML, you can learn the basics in a day. Since we are looking about how long it takes to build a real-world project, this is the list of things you need to learn:

• How React works
• JSX
• State
• Props
• Main Hooks
  • useState
  • useEffect
  • useRef
  • useMemo
• Components
• NPM, Bebel, Webpack, ES6+
• Functional Components vs Class Components
• React Router
• Create React App, Next.js, or Gatsby
• Optional but recommended: Redux, Recoil, Zustand, or Providers

Vue

In my opinion, Vue takes a bit more time than React to build a real project. With a bit of work, you could learn the Vue fundamentals in less than 3 days. Although Vue takes longer to learn, it is definitely one of the fastest popular Javascript frameworks to learn. Here is the list of things you need to learn:

• How Vue Works
• .vue files
• NPM, Bebel, Webpack, ES6+
• State management
  • Vuex
• Components
• create-vue-app/Vue CLI
• Vue Router
• Declarative Rendering
• Conditionals and Loops
• Vue Instance
• Vue Shorthands
• Optional: Nuxt.js, Vuetify, NativeScript-Vue

Angular

Angular is a massive framework, much larger than any other in this comparison. This may be why Angular is not as performant as other frameworks such as React, Svelte, or Vue. To learn the basics of Angular, it could take a week or more. Here are the things you need to learn to build a real-world app in Angular:

• How Angular Works
• Typescript
  • Data Types
  • Defining Types
  • Type Inference
  • Interfaces
  • Union Types
  • Function type definitions
• Two-way data binding
• Dependency Injection
• Components
• Routing
• NPM, Bebel, Webpack, ES6+
• Directives
• Templates
• HTTP Client

Svelte

One could argue that Svelte is the easiest framework to learn in this comparison. I would agree with that. Svelte's syntax is very similar to an HTML file. I would say that you could learn the Svelte basics in a day. Here are the things you need to learn to build a real-world app in Svelte:

• How Svelte Works
• .svelte files
• NPM, Bebel, Webpack, ES6+
• Reactivity
• Props
• If, Else, Else ifs/Logic
• Events
• Binding
• Lifecycle Methods
• Context API
• State in Svelte
• Svelte Routing

Wrapping up the 4th Factor: Learning Curve

All these frameworks (especially Vue, Svelte, and React) are extremely easy to learn, very much so when one is already proficient with Javascript and HTML. Let's rank these technologies in terms of their learning curve!

(ordered in fastest to learn to longest to learn)

1. Svelte
2. React
3. Vue
4. Angular

The 5th Factor: Real-world examples

In this factor, the final factor, we will be looking at some real-world examples of apps using that particular framework. At the end of this factor, the technologies won't be ranking but it's up to you to see which of these framework's syntax and way of doing things you like best. Let's dive right into it!

React

Top 5 Real-world companies using React: Facebook, Instagram, Whatsapp, Yahoo!, Netflix

Displaying "Hello World" in React:

import React from 'react';

function App() {

   return (

      <div>

         Hello World

      </div>

   );

}

Vue

Top 5 Real-world companies using Vue: NASA, Gitlab, Nintendo, Grammarly, Adobe

Displaying "Hello World" in Vue:

<template>

    <h1>Hello World</h1>

</template>

Angular

Top 5 Real-world companies using Angular: Google, Microsoft, Deutsche Bank, Forbes, PayPal

Displaying "Hello World" in Angular:

import { Component } from '@angular/core';

@Component ({

   selector: 'my-app',

   template: <h1>Hello World</h1>,

})

export class AppComponent;

Svelte

Top 5 Real-world companies using Svelte: Alaska Air, Godaddy, Philips, Spotify, New York Times

Displaying "Hello World" in Svelte:

<h1>Hello world</h1>

Wrapping up the 5th Factor: Real-world Examples

Wow! Some huge companies that we use on a daily basis use the frameworks that we use. This shows that all of these frameworks can be used to build apps as big as these household names. Also, the syntax of all of these frameworks is extremely intuitive and easy to learn. You can decide which one you like best!

Conculsion

I know, you're looking for a ranking of all of these frameworks. It really depends but to fulfil your craving for a ranking, I'll give you my personal opinion:

1. Svelte
2. React
3. Vue
4. Angular

This would be my ranking but based on these 5 factors, choose whichever framework you like best and feel yourself coding every day in, all of them are awesome. I hope that you found this article interesting and maybe picked a new framework to learn (I'm going to learn Svelte)! Please let me know which frontend framework you use and why you use it. Thanks for reading!

Comments

[stefanovualto]

Hi Henry,

I mostly agree with the point 1,2,3.

But point 4 is subjective depending on your background and previous knowledge. To improve your post, you should add a note explaining what's your background.

Finally point 5 are not similar at all. The vue example is a complete page using a reactive property.

Anyway as @johnpapa said in a talk, you can achieve almost the same result with any framework, pick the one which feels right for you... :)

[Henry Boisdequin]

Yes, I agree with you! I would recommend anyone to learn the framework which feels right for you.

For the Vue example, I'm not an expert at Vue and don't know a better way to do it (if you have a smaller, more concise 'hello world' example, please comment it).

I will definitely work an a 'what's my background section'. To explain it know: I've been using React in all my web dev projects. I have basic knowledge of Vue, Angular, and Svelte. After looking at these 5 factors, I plan to use Svelte for my coming projects.

Thanks, @stefanovualto for the feedback!

[Christopher Wray]

In the Vue example you are using data components. For the others just plain html. You could have a Vue component with a template of just the h1 tag and no script. It would look more like the svelte example.

[Henry Boisdequin]

✅

[stefanovualto]

In your vue example, I think that you should expect to be in a .vue file lik le it seems to be in the others (I mean that you have the whole bundling machinery working under the hood). Then something similar would be:

<template>
    <h1>Hello world!</h1>
</template>

Maybe a pro' for vue is that it can be adopted/used progressively without having to rely on building process (which I am assuming are mandatory for react, svelte and maybe angular). What I mean is that your previous example worked, but it wasn't comparable to the others.

[Zen]

I'm usually using Svelte for my projects. Because, it's simple, write less, and get more

[Ryan Carniato]

A couple thoughts.

"Requires JSX" a downside??? I almost stopped reading at that point. Template DSLs are more or less the same. If that's a con, doesn't support JSX could easily be seen as one. There are reasonable arguments for both sides and this shows extreme bias.

Vue is "truly reactive" as well. Whatever that means.

Your JS Framework Benchmark results are over 2 years old. Svelte and Vue 3 are both out and in the current results. He now publishes them per Chrome version. Here are the latest: krausest.github.io/js-framework-be.... It doesn't change the final positions much, but Svelte and Vue look much more favorable in newer results.

If anyone is interested in how those benchmarks work in more detail I suggest reading: dev.to/ryansolid/making-sense-of-t...

[Henry Boisdequin]

I'm a React dev and it's my favourite framework out of the bunch. When I did some research and asked some other developers when they think of React they think of needing to learn JSX. For something like Svelte, all you need to know is HTML, CSS, and JS.

I know that my benchmarks were two years old and I addressed this multiple times before:

For the performance factor, I knew that the frameworks were a bit outdated but the general gist stated the same. Svelte 3 was released some time ago and that blows all of the other frameworks out of the water in terms of performance hence Svelte would stay on top. Vue and React are very similar in performance, Vue even says so themselves: vuejs.org/v2/guide/comparison.html. Since, Angular is a massive framework with built-in routing, etc, its performance didn't become better than Vue, React, or Svelte in its newer versions.

Thanks for the new benchmark website, I will definitely be using that in the future. Also, I just read your benchmark article and its a good explanation on how these benchmarks work.

Thanks for your input.

[Ryan Carniato]

Here's the index page where he posts new results as they come up: krausest.github.io/js-framework-be...

When I did some research and asked some other developers when they think of React they think of needing to learn JSX. For something like Svelte, all you need to know is HTML, CSS, and JS.

Svelte has good marketing clearly.

Is this HTML?

<label>
    <input type="checkbox" bind:checked={visible}>
    visible
</label>

{#if visible}
    <p transition:fade>
        Fades in and out
    </p>
{/if}

Or this HTML?

<a @[event]="doSomething"> ... </a>
<ul id="example-1">
  <li v-for="item in items" :key="item.message">
    {{ item.message }}
  </li>
</ul>

How about this?

<form onSubmit={handleSubmit}>
  <label htmlFor="new-todo">
     What needs to be done?
   </label>
   <input
      id="new-todo"
      onChange={handleChange}
      value={text}
    />
    <button>
       Add #{items.length + 1}
    </button>
</form>

[Henry Boisdequin]

That's why a con of Svelte is its syntax (I added that in my post). This is more explanation to that point:

Firstly, for confusion in variable names, I'm talking about how Svelte handles state. Coming from React, state would only be initialized with the useState hook. In Svelte, all the variables you make is state which could be confusing for someone just learning Svelte. Also, for the confusion in syntax, I'm talking about the confusion in logic. For example, if statements in Svelte are different than the usual Javascript if statements which could cause some confusion/more learning time for beginners. There are also other examples of this.

[Zen]

why svelte is not seen in search trend? because, svelte's docs is very easy to new comer in this framework

[Henry Boisdequin]

I'm not really sure @mzaini30 . A great pro of Svelte is its docs and tutorial on its website. I think in 1-2 years, you are going to see Svelte at least where Vue is in the search trends.

Most of the search trends come from developers asking questions like how to fix this error, or how to do this but since not many people use Svelte (compared to the other frameworks) there are not many questions being asked.

[Bergamof]

Sure! Too bad the great Svelte tutorial was not mentioned.

[Henry Boisdequin]

It's a great tutorial, but I decided to just add video tutorials. In the community factor, I give a link to the Svelte community website which features that tutorial!

[dallgoot]

I don't want to start a flamewar but i see a trend where React is considered the -only- viable framework and -some- people reacting like religious zealots against any critics because "it's the best ! it's made by Facebook!"
React is too hyped IMHO.
Svelte is a a true innovation. And yes performance matters.
Angular and Vue may lose traction with time... i think... i fail to see their distinctive useful points.

[Henry Boisdequin]

I completely agree with you. Most React devs now will not try any other framework and just make fun of the others. I completely agree that React is too hyped. Unfortunately, as you stated, Angular and Vue are losing some traction. I also agree with you that Svelte is a true innovation, this is why I put Svelte at number 1! For 2021, I will focus on using Svelte. Thanks for reading!

[Sergiy Yevtushenko]

Sad that Solid not even mentioned, although it's the one of the best performing frameworks.

[Henry Boisdequin]

I've never actually heard of solid. I'll check it out!

[Sergiy Yevtushenko]

Well, author of the Solid is even commented in this topic.

[Ryan Carniato]

To be fair, performance is only one area and arguably the least important. Even if Solid completely dominates across the board in all things performance by a considerable margin, we have a long way before popularity, community, or realworld usage really makes it worth even being in a comparison of this nature. But I appreciate the sentiment.

[Sergiy Yevtushenko]

Well, good performance across the board usually is a clear sign of high technical quality of design and implementation.

[Shriji]

Also, it would be great if you could give a little explanation of this point

Confusion in variable names and syntax

[Henry Boisdequin]

Firstly, for confusion in variable names, I'm talking about how Svelte handles state. Coming from React, state would only be initialized with the useState hook. In Svelte, all the variables you make is state which could be confusing for someone just learning Svelte. Also, for the confusion in syntax, I'm talking about the confusion in logic. For example, if statements in Svelte are different than the usual Javascript if statements which could cause some confusion/more learning time for beginners. There are also other examples of this.

[Shriji]

It makes syntax simpler TBH. React isn't even a direct comparison to Svelte. The only syntax that users will get accustomed to is $ assignments.

[Sylvain Simao]

React with a smaller learning curve than Vue.js 🤔

[Henry Boisdequin]

They were very tight but I would say that React has a smaller learning curve as its more intuitive and has easier syntax than Vue.

[Sylvain Simao]

Sorry @hb, you've decided to go on a touchy subject by writing this article! I will have to disagree with you on that point.

I think it's perfectly okay to prefer using React. There are many reasons why it is a good choice. However, an easy learning curve isn't part of it.

Just so there is no ambiguity, after having used all the Frameworks from this article - my choice goes towards Vue.js and Svelte, but I'll try to remain as objective as possible.

1) According to the State of JS survey 2018 (not using 2019, because that same question wasn't part of last year's survey). From 20,268 developers interrogated, the number #1 argument about Vue.js is an easy learning curve. For React it comes at position #11 (top 3 beings: elegant programming style, rick package ecosystem, and well-established):

2018.stateofjs.com/front-end-frame...
2018.stateofjs.com/front-end-frame...

2) Main reason why Vue.js is labelled "The Progressive JavaScript Framework", is because it is progressive to implement and to learn. Before you can get started with React, you need to know about JSX and build systems. On the other end, Vue.js can be used just by dropping a single script tag into your page and using plain HTML and CSS. This makes a huge difference in terms of approachability of the Framework.

3) Maybe less objective on this one - but from my own professional experience with both Frameworks and leading teams of developers - it usually takes Junior Developers almost twice the time to become proficient with React than with Vue.js. Firstly because of what I mentioned in point number 2. Secondly, because React has few abstraction leaks that makes performance optimisation something developers have to deal with themselves (using memoize hooks). It's a concept that is hard to understand, but essentials if working on large applications. Thirdly, because of the documentation (as you mentioned in your article). And lastly because of the fragmented ecosystem of libraries that can quickly be overwhelming for Junior Devs.

Again, I think there are a lot of reasons why React can be a good choice. But not because of the learning curve.

[Thorsten Hirsch]

Angular 6? Well, they just released version 11 and there was the switch to Ivy since version 6, so what about a more recent benchmark? And looking at the Google trends chart I wonder why all 3 (React/Angular/Vue) lost quite a bit of their popularity during the past months... any new kid on the block? It's obviously not Svelte, which could hardly benefit from the others' losses.

[Henry Boisdequin]

For the performance factor, I knew that the frameworks were a bit outdated but the general gist stated the same. Svelte 3 was released some time ago and that blows all of the other frameworks out of the water in terms of performance hence Svelte would stay on top. Vue and React are very similar in performance, Vue even says so themselves: vuejs.org/v2/guide/comparison.html. Since, Angular is a massive framework with built-in routing, etc, its performance didn't become better than Vue, React, or Svelte in its newer versions.

For the search results, they are unpredictable. To my knowledge, there is no new kid on the block in terms of frontend Javascript frameworks. If anything, more people are using Web Assembly. As you can see from the search results graph, it goes up and down, changing all the time.

[Shriji]

You forgot to mention that Svelte has a great discord :)

[Henry Boisdequin]

I just had a look at it, a great tool! I'll add it to the post!
