random number javascript
/* The Math.random() function returns a floating-point, pseudo-random number in the range 0 to less than 1 (inclusive of 0, but not 1) with approximately uniform distribution over that range — which you can then scale to your desired range. The implementation selects the initial seed to the random number generation algorithm; it cannot be chosen or reset by the user. */ function getRandomInt(max) { return Math.floor(Math.random() * Math.floor(max)); } console.log(getRandomInt(3)); // expected output: 0, 1 or 2 console.log(getRandomInt(1)); // expected output: 0 console.log(Math.random()); // expected output: a number from 0 to <1
