Random Number Generator using ReactJS

by Abdul Rawoof A R Updated: Jan 24, 2023

In this kit, we're going to create random number generator using reactjs with simple steps. Javascript creates pseudo-random numbers with the function Math. random() . This function takes no parameters and creates a random decimal number between 0 and 1. The returned value may be 0, but it will never be 1. Math.random() returns a random number between 0 (inclusive), and 1 (exclusive). On every click you'll get an random number. To implement this use the ready-made code snippet below with added required library. Just copy the code and paste it in your IDE. Explore more top trending libraries and snippets on kandi.

Code

In this solution we are using React library.

import React from 'react';
import { render } from 'react-dom';

class Button extends React.Component {

  constructor(props) {
    super(props);
    this.handleClick = this.handleClick.bind(this);
    this.state = { random: 0 };
  }

  handleClick() {
    const min = 1;
    const max = 100;
    const rand = min + Math.random() * (max - min);
    this.setState({ random: this.state.random + rand });
  }

  render() {
    return (
      <div>
        <button onClick={this.handleClick.bind(this)}>Click</button>
        <div>The number is: {this.state.random}</div>
      </div>
    );
  }
}

render(<Button />, document.getElementById('container'));

Instructions

Follow the steps carefully to get the output easily.

Install the Node.js and React on your IDE(preferable Visual Studio Code).
Create React Application using npx create-react-app foldername.
cd foldername.
Open the folder in IDE.
Copy the code using "copy" button above and paste it in index.js file(remove the earlier code from index.js).
Open the terminal from IDE.
npm start to run the file.

I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.

I found this code snippet by searching for 'how to create random number generator using reactjs' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

The solution is created in Visual Studio Code 1.73.1.
The solution is tested on node v18.12.1 and npm v8.19.2.
React version-18.2.0.

Using this solution, we are able to create random number generator using reactjs with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to create random number generator using reactjs.
