How to add map method to TypedArray in browsers other than Mozilla 38+?

Question

JavaScript

Code example:

"use strict";
var arrayOfInitialPositions = ;
var lambdaDistance = [0.005, 1.005, 2.005];
for (var i = 0, len = arrayOfInitialPositions.length-1; i < len-1; i++)
{
arrayOfInitialPositions[i].map(function(item,j,array){ return (arrayOfInitialPositions[i+1][j] * lambdaDistance[i]) });
}

In Mozilla 38+ everything will work fine, in other browsers there will be an error.
