Use the Math.random() Method

You can simply use the Math.random() method in combination with the Math.floor() method to generate a random number between two numbers in JavaScript.

The Math.random() method returns a floating-point, pseudo-random number in the range 0 to less than 1 (inclusive of 0, but not 1), whereas the Math.floor() method round the number down to the nearest integer. Let's take a look at the following example to see how it works:

/* Defining a custom function which returns a random number 
between min and max, including min and max */
function generateRandomNumber(min, max) {
    return Math.floor(Math.random() * (max - min + 1) + min);
}

// Generate a random number between 1 and 10 (including 1 and 10)
var randomNum = generateRandomNumber(1, 10);
console.log(randomNum);
