The world's easiest, most powerful random function.

Rando.js helps JavaScript developers code randomness more simply, readably, and securely. Whether you need to find a random int/float between two numbers, pick a random value from an array, choose a random element from your jQuery object, grab a character from a string, toss a coin, or do anything of the like while even preventing repetitions, we've got you covered at a cryptographically strong level. The best part? Our library is extremely lightweight and developer friendly- which means it won't take a toll on your project, and it's uber-simple to implement.
