How to Generate a Random Number between Two Numbers in JavaScript
Topic: JavaScript / jQueryPrev|Next
Answer: 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:
Example
Try this code »/* 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);
