How React's ES6 syntax is different from ES5 syntax?

1. require vs. Import // ES5 var React = require('react'); // ES6 import React from 'react';

2. exports vs. export

// ES5 module.exports = Component; // ES6 export default Component;

 3. component and function

// ES5 var MyComponent = React.createClass({ render: function() { return( <h3>Hello JavaTpoint</h3> ); } }); // ES6 class MyComponent extends React.Component { render() { return( <h3>Hello Javatpoint</h3> ); } }

4. props

// ES5 var App = React.createClass({ propTypes: { name: React.PropTypes.string }, render: function() { return( <h3>Hello, {this.props.name}!</h3> ); } }); // ES6 class App extends React.Component { render() { return( <h3>Hello, {this.props.name}!</h3> ); } }

Here is a great JavaScript interview question! What the heck is a Promise doing under the hood? In JavaScript, things usually happen one after the other. It's like a checklist each item gets done before moving to the next. When a function returns a Promise, it's like making a promise to do something, like fetch data from the internet. But JavaScript doesn't wait around for the data to come back. Instead, it moves on to the next task. Now, here's where things get interesting. While JavaScript is busy doing other stuff, like running more code, the Promise is off fetching data in the background. Once the data is fetched, the Promise is fulfilled, and it has some information to share. But JavaScript needs to know when it's time to handle that information. That's where the onFulfilled part of the Promise comes in. When the Promise is fulfilled, JavaScript takes the onFulfilled code and puts it in a special queue, ready to be run. Now, async/await enters the scene. When we mark a function as async, we're telling JavaScript, "Hey, this function might take some time to finish, so don't wait up for it." And when we use the await keyword inside an async function, it's like saying, "Hold on a sec, JavaScript. I need to wait for something important before moving on." So, when JavaScript encounters an await keyword, it pauses and lets the async function do its thing. If that thing happens to be a Promise, JavaScript knows it can move on to other tasks while waiting for the Promise to resolve. Once the Promise is resolved, JavaScript picks up where it left off and continues running the code. Promises and async/await allow JavaScript to handle asynchronous tasks while keeping things organized and in order. Promises handle the background tasks, while async/await makes it easier to work with them in our code, ensuring everything happens in the right sequence.

9 tips to write better JavaScript code: Use const and let instead of var Keep functions pure and focused Avoid deeply nested callbacks (use Promises or async/await) Use arrow functions for cleaner syntax Always handle errors in async code Keep your code modular and reusable Use strict equality === instead of == Comment only when necessary — write self-explanatory code Understand closures, hoisting, and scope Web Development Resources ⬇️ https://whatsapp.com/channel/0029VaiSdWu4NVis9yNEE72z ENJOY LEARNING 👍👍
