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

js math.random

/*
`Math.random` returns a pseudo-random number between 0 and 1.

pattern
*/

Math.random(); // -> Decimal number between 0 and 1

Math.round(Math.random()); // -> 0 or 1

Math.random() * max; // -> Decimal number between 0 and max

Math.floor(Math.random() * max); // -> Whole number between 0 and max - 1

generating random number in javascript
