javascript create array from for loop

Question

I have a years range stored into two variables. I want to create an array of the years in the range.

something like:

var yearStart = 2000;
var yearEnd = 2040;

var arr = [];

for (var i = yearStart; i < yearEnd; i++) {

     var obj = {
        ... 
     };

      arr.push(obj);
}

What should I put inside the obj ?

The array I'd like to generate would be like:

arr = [2000, 2001, 2003, ... 2039, 2040]

Answer 1

even shorter if you can lose the yearStart value:

var yearStart = 2000;
var yearEnd = 2040;

var arr = [];

while(yearStart < yearEnd+1){
  arr.push(yearStart++);
}

UPDATE: If you can use the ES6 syntax you can do it the way proposed here:

let yearStart = 2000;
let yearEnd = 2040;
let years = Array(yearEnd-yearStart+1)
    .fill()
    .map(() => yearStart++);
