Hi..

I want to generate random numbers (integers) in javascript within a specified range. ie. 101-999. How can I do that. Does Math.random() function supports range parameters ?

Answer 1

Just scale the result:

function randomInRange(from, to) {
  var r = Math.random();
  return Math.floor(r * (to - from) + from);
}
