🧠 Understanding useState, useEffect, and useRef in React (with Simple Examples)

Satya Samaikya Venna — Thu, 22 May 2025 07:21:03 +0000

React is a powerful JavaScript library for building user interfaces. If you're new to React or hooks, you might be wondering what these things are:

useState
useEffect
useRef

These are React Hooks — functions that let you use state and other React features without writing a class.

In this blog, let's explore each one with simple examples and easy explanations.

🔄 useState - Managing State in Functional Components

The useState hook allows you to add state to your functional components.

✅ Syntax

const [state, setState] = useState(initialValue);

🧪 Example: Counter App

import React, { useState } from 'react';

function Counter() {
  const [count, setCount] = useState(0);

  return (
    <div>
      <h2>Count: {count}</h2>
      <button onClick={() => setCount(count + 1)}>Increase</button>
    </div>
  );
}

export default Counter;

📘 Explanation

count is the state variable.
setCount is the function to update count.
useState(0) initializes the count with 0.

⚙️ useEffect – Side Effects in Components

The useEffect hook lets you perform side effects like:

Fetching data
Updating the DOM
Subscribing to events

✅ Syntax

useEffect(() => {
  // Your code here
}, [dependencies]);

🧪 Example: Log Count Changes

import React, { useState, useEffect } from 'react';

function CounterWithEffect() {
  const [count, setCount] = useState(0);

  useEffect(() => {
    console.log(`Count has changed to: ${count}`);
  }, [count]);

  return (
    <div>
      <h2>Count: {count}</h2>
      <button onClick={() => setCount(count + 1)}>Increase</button>
    </div>
  );
}

export default CounterWithEffect;

📘 Explanation

The useEffect runs after the component renders.
It only runs again when count changes because of the [count] dependency.

🧷 useRef – Referencing DOM Elements or Storing Values

The useRef hook gives you a way to:

Access DOM elements directly
Store mutable values that don’t cause re-renders

✅ Syntax

const myRef = useRef(initialValue);

🧪 Example: Focus an Input

import React, { useRef } from 'react';

function FocusInput() {
  const inputRef = useRef(null);

  const handleFocus = () => {
    inputRef.current.focus();
  };

  return (
    <div>
      <input ref={inputRef} type="text" placeholder="Type here..." />
      <button onClick={handleFocus}>Focus Input</button>
    </div>
  );
}

export default FocusInput;

📘 Explanation

inputRef is linked to the input using ref={inputRef}.
inputRef.current gives you access to the actual DOM element.
Clicking the button focuses the input.

✅ Summary Table

Hook	Purpose	Triggers Re-render?	Example Usecases
useState	Add local state to a component	✅ Yes	Counter, Form inputs
useEffect	Run side-effects (after render)	✅ Depends on deps	API calls, timers
useRef	Access DOM or store mutable values	❌ No	Focus input, timer IDs

🚀 Final Thoughts

React Hooks make it easier to write clean, functional components without the complexity of classes. Here's a quick rule of thumb:

Use useState to store values that change and affect UI.
Use useEffect to handle side effects like fetching data or setting up subscriptions.
Use useRef when you want to persist values or directly interact with the DOM.

Happy Coding! 🎉

Functional Components vs Class components in React

Satya Samaikya Venna — Thu, 15 May 2025 21:04:31 +0000

Introduction

React offers two main ways to define components: Functional and Class-based. Over time, functional components have become the standard, especially with the introduction of React Hooks in version 16.8. In this post, we’ll break down both types, explore their differences, and help you understand when and why to use one over the other.

🔹 What Are React Components?

Components are the building blocks of any React application. Each component represents a piece of UI. There are two primary types:

Functional Components
Class Components

🔹 Functional Components

✅ Definition
A functional component is a plain JavaScript function that returns JSX. Before hooks, functional components were limited and couldn't manage state or side effects — now they can do almost everything class components can.

import React from 'react';

function App(){
    return(
       <div>
         <h1>Hello World</h1>
       </div>
 )
}
export default App;

✅ Advantages

Concise and easier to read
No need for this keyword
Full feature support via Hooks
Preferred in modern React development

🔹 Class Components

✅ Definition
Class components are ES6 classes that extend from React.Component. They have a render() method and access to lifecycle methods.

import React, { Component } from 'react';

class App extends Component{
      render(){
         return(
            <div>
               <h1>Hello World</h1>
            </div>
      )
}
export default App;

❗ Drawbacks

More boilerplate
Use of this can be confusing
Lifecycle methods are less intuitive than hooks

🔹 Comparison Table

Feature	Functional Component	Class Component
Syntax	Function/Arrow Function	ES6 Class
State	useState Hook	this.state
Side Effects	useEffect Hook	Lifecycle methods
this keyword	❌ Not required	✅ Required
Boilerplate	Minimal	Verbose
Code Reusability	Custom Hooks	HOCs, Render Props
Performance	Slightly better (modern)	Slightly heavier

🔹 When to Use Functional Components

In modern React projects (React 16.8+)
When you want concise, maintainable code
When using hooks for shared logic

🔹 When Class Components Are Still Useful

Maintaining legacy codebases
Understanding React's history and lifecycle
Some advanced patterns still use classes (e.g., Error Boundaries)

🔹 Conclusion

While both functional and class components are valid in React, the trend has shifted toward using functional components thanks to the power of hooks. They make code easier to understand, test, and maintain.

If you’re starting a new project or migrating old code, go with functional components — they're the future of React.

✍️ Final Thoughts

React continues to evolve, and staying updated is essential. Embracing functional components and hooks will help you write cleaner, more efficient React apps.

Array Methods in Javascript

Satya Samaikya Venna — Wed, 07 May 2025 20:32:12 +0000

Introduction to JavaScript Arrays:

Arrays store multiple values in a single variable.
Can hold different data types.
Indexed starting from 0.
Ex: array=[1,2,3,4,5]
Creating an empty array.Ex: arr=[];
Creating an array and initialise it.

Adding or Removing Items:

push(): Adds an element to the end.
pop(): Removes the last element.
shift(): Removes the first element.
unshift(): Adds an element to the beginning.
length: Returns the number of elements.

Iteration Methods:

ForEach(): Executes a function for each element.

map(): Creates a new array by applying a function.
Reduce():Accumulates values into a single element.

Searching and Filtering:

filter():Returns all matching elements.
find():Returns first element that satisfies the condition.

Extracting / Copying:

Slice(): Extracts a portion of an array.

Updated Section: Modifying and merging arrays

splice() – Add, Remove, or Replace (Mutates Original)

concat() – Merge Arrays (Does NOT Mutate Original)

Conclusion:

Enhance efficiency and readability to the code.
Useful for adding,removing, searching,iterating and transforming data.
JavaScript provides powerful array methods.

Javascript Vs Typescript

Satya Samaikya Venna — Tue, 25 Feb 2025 19:14:46 +0000

JavaScript vs TypeScript

JavaScript

JavaScript is a dynamic, high-level scripting language primarily used for web development. It is interpreted and loosely typed, making it flexible but also prone to runtime errors.

Pros:

Widely supported in all browsers
Simple syntax and easy to learn
Large ecosystem and community support
No compilation required

Cons:

No static type checking
Prone to runtime errors
Hard to manage large-scale applications

TypeScript

TypeScript is a superset of JavaScript that adds static typing and advanced features to enhance code quality and maintainability. It compiles to JavaScript, ensuring compatibility with existing JS environments.

Pros:

Static typing reduces runtime errors
Better code organization for large projects
Supports modern JavaScript features
Improved IDE support with autocompletion and refactoring tools

Cons:

Requires compilation
Learning curve for developers unfamiliar with static typing
Not supported natively in browsers (needs transpilation to JS)

Conclusion

JavaScript is great for quick development and small projects, while TypeScript is ideal for large-scale applications requiring better maintainability and type safety.
