Why A Developer Should Learn Reactjs?

Learning new skills is always nice but you should learn something that actually will turn out fruitful in future. Choose a skill that is worth your time and money. Learning React JS is good to start because it is very popular throughout the globe among web developers.

About React.js
React(also known as React.js or React JS) is an open-source, front end, JavaScript library for building user interfaces or UI components. It is maintained by Facebook and a community of individual developers and companies. React Image

React.js is one of the most critical front-end libraries you can use in modern JavaScript development. It enables you to build highly reactive user interfaces that provide a fast and mobile-app-like user experience.

Popularity
React.js is already extremely popular. Its popularity has risen continuously over the past years, and I see absolutely no reason why that should change.

It is vastly used by professional developers and there are plenty of job opportunities in the digital field for anyone who has command over React JS. React is a Javascript library that is simple to its users and uses minimal coding. In short, it won't be incorrect if we say that React simplifies the life of a developer.

Importance Of Learning React
Mastering React can enable you to get hold of a lucrative and financially rewarding job. There is a strong market demand for people who are well versed in React as it is used to create both web and mobile applications. One should never have second thoughts about perusing courses to learn React.

It will focus on being a library for component-based UI creation - with all its strengths and weaknesses. The future of React.js is very bright.With the power of modern JavaScript and ReactJs, the web development becomes exiting and addictive.

Again, knowing general web developer skills like HTML, CSS, and JavaScript is a must for working as a web developer, but the more skills like React that you stack on top of your foundation, the more in-demand you will be to employers and the more money you can earn. And when you look at the time investment it takes to learn a skill like React JS (literally a handful of months) that investment becomes a no-brainer. Part of being a successful web developer is staying on top of current technologies, and right now .React is at the top of the web technology heap.
Once you learn React with your full potential and learn full features of React, you probably never gonna think to leave React.

So that was it from this article😇. Please share your thoughts/comments/feedback.

The community is drunk.

Svelte, Vue, Riot, and others are objectively lighter, easier, and more standards-compliant (clean markup, custom events, Web Components).

This morning I just reviewed a candidates take-home that was all done in state-of-the-art React. It was good React, but I felt like I was staring at old jQuery spaghetti code. Painfully over-engineered, highly fragmented and abstract, but that's React.

Get out of your bubble and get sober folks! And hiring managers, STOP with the "React developer" job postings. You're ruining the talent pool.

I think, spaghetti code comes from bad developers, not from any languages/libs/frameworks.

I thought so too, but I've learned there's strong influences inherent in React that pull you in that direction. Even the React team at Fb can't avoid it:

We’ve often had to maintain components that started out simple but grew into an unmanageable mess of stateful logic and side effects.
reactjs.org/docs/hooks-intro.html#...

And

If you look at a typical React application in React DevTools, you will likely find a “wrapper hell” of components surrounded by layers of providers, consumers, higher-order components, render props, and other abstractions.

  1. Every codebase will easy become a mess with complicated-logic and low-scale strategy, React hooks help us easier to build component, it doesn't mean react class component can not expand, it's just a update of react like VueJS composition API (I see it's just same idea, structure compare to hooks).
  2. React DevTools just shows us the truth of our project, using js-frameworks means you have to deal with so much abstract layers, you can debug every things in project, it works well everyday, its just like you debug html element and that's why its not problem. btw, you and me can use anything we love and frameworks war means nothing. They are just tools to help us solving problems, if you understand one enough, you can do everything with them.

Too late unfortunately. React was a dream come true for all the resume/hype driven programming people out there. Now everyone is migrating their codebases to React just because everyone is using it. But, hell if you need to find a job its your best bet. Until you have a look at the codebase and cry yourself to sleep.
But as I said, if you need to get a job to support yourself and your family its the best option this time around.

Believe it or not, I wrote a post arguing against React and other frameworks, but since it is so popular, the main focus became React. Honestly, people were out for my blood. It wasn't a pleasant experience and I removed the post.

Newbie developers, I don't blame them. They are jumping onto the hype-train because of the "senior" developers that are utterly biased and can't see beyond their opinions. They're making the community toxic.

Ah, shouldn't have removed it. I would have liked to read it. Just ignore the comments as it's just your opinion. If people don't like it that is their problem :)

I think the same could be said for Vue 2. The components start off small, then blow up. This is partly due to the Options API. I believe the introduction of the Composition API in Vue 3 will aid in writing readable and maintainable components.

I never experience that with Vue 2, but I do have a slightly different approach to my structuring of components (see dev.to/jfbrennan/helpful-patterns-...)

I worked with Angular for a year and now I am facing problems joining new companies.
Everyone today wants React.

Don't lose hope, as a developer you have to update yourself!👍🏻

total agreed, I can work with both React and Vue, if some day my job requires me to learn Angular, I will be ready, it's all about javascript and the DOM :D

Technology will change through the years. We just need to adapt, and spaghetti code can happen in any language/framework.
People think of JavaScript as a bad language... I think it is just different, it's more dynamic so demands more self strictness and cleaness to write good code. I've seen spaghetti code in Java, C#, Python.... I think we should be aware of other tech available and understand their strengths and drawbacks because in the end they are all tools. My first OOP program was a mess.... as was my React, till I got into it deeper and learn how to better code for that language/framework. Don't hate on different techs, just know that there's not only one source of Truth. jQuery is still by far the most used JavaScript framework on the web. 😉

In the end, it doesn't matter if you pick React, Angular, Vue, Svelte, or jQuery.
Every application starts small and well thought, but eventually, it will grow into a large codebase and complexity. You can't avoid that.

There is no way that React, Angular, Vue, or Svelte is better than the other. They are maybe more suitable for different scenarios.

Yes, React is simple to start. It offers a lot of freedom if you compare it to Angular. There is a lot of freedom to pick other libraries in combination with React, but this comes with a significant amount of responsibility. Next to the responsibility, not every React developer will use the same thing for state management. So the knowledge is more widely spread.

Compare that to Angular. Angular is a framework with a lot of things in it. It offers less freedom but takes responsibility for you instead of moving that to you. Most developers that are using Angular are familiar with the same things (some details will differ).

So what is the best framework? It's up to you! It's up to the company you are working for and the application your building.

But even though the popularity will differ, there is no framework/library to rule them all 😉

Sorry, unrelated to the OP but a lot of hate for react, I'm a beginner so I don't know an awful lot; however, the extensive amount of content I've found for react has made me a better JS developer.

On the other hand, I really like Angular and want to use it more. If there's a lot of hate for react, how does angular sound?

I know, I know.... I just hate React. Maybe I'll stick to dev jobs that don't work with javascript or browsers.
