In this tutorial, we will learn how to generate random numbers in javascript and we use a special method in javascript i.e.The Math.random() static method returns a floating-point, pseudo-random number that’s greater than or equal to 0 and less than 1, with approximately uniform distribut...

I just looked at your javascript random number generator. I wanted to generate a number from 1-3 with even odds and used ceil. What I was wondering about was whether I could ever get a 0 -- since random could conceivably generate a 0, this looked conceivable, so I added code to cover...
What it doesn't give us is a random number that is cryptographically secure. If you are planning on using a random number generator for some security intensive activities like generating a certificate or authenticating someone, Math.random() isn't a secure option. The reason is that a clever...
We can use the Math.floor() function to round our random number up to become a random integer, and we can multiply that number to generate a larger one. Here’s an example of a random number generator function in JavaScript: var random_number = Math.floor(Math.random() * 10); console...
ckknight/random-js Random.js This is designed to be a mathematically correct random number generator library for JavaScript. Inspiration was primarily taken from C++11's<random>. Upgrading from 1.0 Upgrading from 1.0 to 2.0 is a major, breaking change. For the most part, the way exports are...
Many of msrCrypto's crypto algorithms require random numbers. Random numbers for cryptography need to be obtained from a cryptographically secure random number generator. This is not available on older browsers (IE10, IE9, & IE8). msrCrypto has its own secure pseudo random number generator (PR...
Math.floor(Math.random() *100) +1; Try it Yourself » A Proper Random Function As you can see from the examples above, it might be a good idea to create a proper random function to use for all random integer purposes. This JavaScript function always returns a random number between min...
