// Random number between 0 and 1 Math.random(); //Random number between 1 and 10 Math.floor(Math.random() * 10) + 1; //Random number between -10 and 10 Math.floor(Math.random() * 20) - 10;
Math.random() function generates a random float value between 0 and 1. To convert that to an integer, multiply the results of
Math.random() by the maximum value you want for the integer and then use
Math.floor() to round it down.
