A Humorous Guide to Mastering ReactJS by Vishal Bairwa

For Developers & TPMs

Welcome Fellow developers & PMs,

to a rollercoaster ride through the whimsical world of React! 🎢 In this blog, we’ll embark on a journey filled with laughter, learning, and a whole lot of code. So buckle up, grab your favorite beverage, and let’s dive into the delightful universe of React JS! 🚀

#1 Components:

Imagine React components as the quirky characters in a sitcom. Each component plays a unique role, contributing to the overall plot of your application. Let’s meet our first character, Mr. Functional Component:

// Functional Component
const Greeting = ({ name }) => {
return <h1>Hello, {name}!</h1>;

And here’s his counterpart, Ms. Class Component:

// Class Component
class Greeting extends React.Component {
render() {
return <h1>Hello, {this.props.name}!</h1>;

Both have their own charm, but remember, sometimes simplicity wins, just like a good ol’ sitcom dad joke. 😄

#2 JSX:

Ah, JSX, the magical syntax that blurs the line between JavaScript and HTML. It’s like writing poetry with code! Here’s a snippet to tickle your fancy:

const element = <div className="container">Hello, JSX!</div>;

Just like adding sprinkles to your ice cream, JSX makes your code sweeter and more delightful! 🍦

#3 Props:

Props are like little gifts that components receive from their parent. They’re passed down like family heirlooms, carrying valuable data. Let’s see how they work:

// Parent Component
const App = () => {
return <Greeting name="Alice" />;

In this scenario, the `Greeting` component receives the `name` prop with the value “Alice” and joyfully displays a personalized greeting.

#4 State:

State is like a mood ring for your component. It reflects its current emotional state and influences its behavior. Here’s a taste of stateful bliss:

class Counter extends React.Component {
constructor(props) {
this.state = { count: 0 };

render() {
return (
<p>Count: {this.state.count}</p>
<button onClick={() => this.setState({ count: this.state.count + 1 })}>

With state, your component can react to user interactions and update its display dynamically. It’s like giving your sitcom character a range of emotions to keep the audience engaged!

#5 Lifecycle Methods:

Think of lifecycle methods as behind-the-scenes directors, orchestrating the show. They manage the lifecycle of your component, from birth to retirement. Here’s a sneak peek at some of the leading roles:

class LifecycleDemo extends React.Component {
componentDidMount() {
console.log('Component mounted!');

componentWillUnmount() {
console.log('Component will unmount!');

render() {
return <h1>Hello, Lifecycle!</h1>;

These methods allow you to perform actions at specific stages of your component’s life, ensuring a smooth performance worthy of a standing ovation! 👏

6. Events:
Events in React are like backstage passes to interact with your components. They trigger actions, create drama, and keep the audience engaged. Here’s a thrilling event handler:

const handleClick = () => {
alert('Button clicked!');

const Button = () => {
return <button onClick={handleClick}>Click me!</button>;

With event handling, you can make your components responsive and interactive, turning your application into a blockbuster hit!

#7 Hooks

Hooks are like modern-day gadgets that streamline your workflow and add a touch of elegance to your code. They’re the superheroes of React, swooping in to save the day! Here’s a heroic example:

import React, { useState } from 'react';

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

return (
<p>Count: {count}</p>
<button onClick={() => setCount(count + 1)}>Increment</button>

With hooks, you can manage state and side effects effortlessly, making your codebase cleaner and more maintainable. It’s like having a trusty sidekick by your side!

# 8 Routing:

Routing in React is like a GPS for your application, guiding users to different destinations seamlessly. It’s the roadmap to success! Here’s a snippet to navigate your way:

import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';

const App = () => {
return (
<Route exact path="/" component={Home} />
<Route path="/about" component={About} />
<Route path="/contact" component={Contact} />

With routing, you can create dynamic, multi-page applications that keep users engaged and entertained. It’s the scenic route to user satisfaction!

#9 Redux

Ah, Redux, the grand conductor of state management in React applications. It’s like having a butler who ensures everything is in its right place. Here’s a glimpse of its regal elegance:

// Reducer
const counterReducer = (state = { count: 0 }, action) => {
switch (action.type) {
return { count: state.count + 1 };
return { count: state.count - 1 };
return state;

// Store
const store = createStore(counterReducer);

// Dispatching Actions
store.dispatch({ type: 'INCREMENT' });
store.dispatch({ type: 'DECREMENT' });

With Redux, you can centralize your application’s state management, making it easier to maintain and scale. It’s the royal decree for a well-organized application!
