function to generate random number in javascript

1//To genereate a number between 0-1
2Math.random();
3//To generate a number that is a whole number rounded down
4Math.floor(Math.random())
5/*To generate a number that is a whole number rounded down between
61 and 10 */
7Math.floor(Math.random() * 10) + 1 //the + 1 makes it so its not 0.

1/* 
2   The Math.random() function returns a floating-point, pseudo-random
3   number in the range 0 to less than 1 (inclusive of 0, but not 1)
4   with approximately uniform distribution over that range — which you
5   can then scale to your desired range. The implementation selects the
6   initial seed to the random number generation algorithm; it cannot
7   be chosen or reset by the user.
