Initialize array with range

Use Array(end-start) to create an array of the desired length, map() to fill with the desired values in a range. You can omit start to use a default value of 0.

var initializeArrayRange = (end, start = 0) =>
  Array.apply(null, Array(end-start)).map( (v,i) => i + start );
