Is There Any Math. Function Which Gives Sequence Of Numbers When Ever I Call It?

I have the following function: function random() { var whichProduct = Math.floor(Math.random()*5); UIALogger.logMessage(whichProduct); } random(); This will give a rando

Solution 1:

I don't think there is anything built in to the language but you can define your own like so:

var increasingSequence = function(a, b) {
  var seq=[], min=Math.min(a,b), max=Math.max(a,b), i;
  for (i=min; i<max; i++) {
    seq.push(i);
  }
  return seq;
};
increasingSequence(1, 5); // => [1, 2, 3, 4, 5]
increasingSequence(2, -2); // => [-2, -1, 0, 1, 2]

Note also that Math.random() returns a value in the range [0,1) (that is including zero but not including one), so if you want your random function to return [1,5] then you should implement it like so:

Math.floor(Math.random() * 5) + 1;
