Create a Component.

Let’s start with the first step.

Step 1: Install and create a new React app.

First you have to install the React project. You should use create-react-app command to create a new React project.

npx create-react-app my-app
cd my-app
npm start

Step 2: Import react component.

After installing, you have to import your React component.

import React, { useState } from 'react';

Step 3: Create a Component.

You can use setTimeout(resolve, ms)); to use delay in react js.

<div>
	<h1>
    aHoisting
	</h1>
		<p>
			This is the initial text.
		</p>
	<button 
			onClick={handleClick}>
				Show Delayed Text
	</button>
			{showDelayedText && (
				<p>
					This text appears after a 
					delay using async/await.
				</p>
			)}
</div>

Use delay example.

The below code is an example of a React. You have to import react and use setTimeout(resolve, ms)); to use delay in react js.

App.js

import React, { useState } from 'react';

function App() {
	const [showDelayedText, setShowDelayedText] = 
		useState(false);

	const delay = async (ms) => {
		return new Promise((resolve) => 
			setTimeout(resolve, ms));
	};

	const handleClick = async () => {
		await delay(2000);
		setShowDelayedText(true);
	};

	return (
		<div>
			<h1>
      aHoisting
			</h1>
			<p>
				This is the initial text.
			</p>
			<button 
					onClick={handleClick}>
				Show Delayed Text
			</button>
			{showDelayedText && (
				<p>
					This text appears after a 
					delay using async/await.
				</p>
			)}
		</div>
	);
}

export default App;

In the above code example, I have used the setTimeout(resolve, ms)); to use delay in react js.

Check the output of the above code.

All the best 👍
