In JavaScript, you can generate a random number using the math.random() function. This function returns a random number between 0 (inclusive) and 1 (exclusive). To generate a random number within a specific range, you can multiply the result by the range and then round down to the nearest integer using the Math.floor() function. For example, to generate a random number between 1 and 10, you can use the following code:

Math.floor(Math.random() * 10) + 1

You can also use the crypto.getRandomValues() method if you want a cryptographically secure random number.

const crypto = window.crypto || window.msCrypto;
const array = new Uint32Array(1);
const randomNumber = array[0] / (0xffffffff + 1);

Note that, the above method will only work in modern browsers that support ‘crypto’ object.
