generating random number in javascript code example

Example 1: how to generate a random number in javascript

//To genereate a number between 0-1
Math.random();
//To generate a number that is a whole number rounded down
Math.floor(Math.random())
/*To generate a number that is a whole number rounded down between
1 and 10 */
Math.floor(Math.random() * 10) + 1 //the + 1 makes it so its not 0.

Example 2: js random number

var random;
var max = 8
function findRandom() {
  random = Math.floor(Math.random() * max) //Finds number between 0 - max
  console.log(random)
}
findRandom()

/*this gives you any random number between a and b
*/
