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.random number javascript
function getRandomNumberBetween(min,max){
return Math.floor(Math.random()*(max-min+1)+min);
}
//usage example: getRandomNumberBetween(20,400);generate random numbers in js
Math.floor((Math.random() * 100) + 1);
//Generate random numbers between 1 and 100
//Math.random generates [0,1)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.
