Hi,

What kind of numbers are you thinking?

function numbers() {
     //define an empty array
      var array = [];
      for(var i=0; i <= 99; i++) {
             //loop through 0 - 99 and push each index as an integer on the array
            array.push(i);
       }
       //return the array to have access to it outside of the function scope
        return array;
}

//Then you can use the function like this
var nums = numbers();
console.log(nums[0]); //will print 0
console.log(nums[99]); //will print 100

Again this depends on which numbers you want to fill into the array. The above is a common for loop that is used to fill an array with numbers.
