Benchmark: Every Third Element

Script Preparation code:

function fillArrayWithNumbers(n) {
        var arr = Array.apply(null, Array(n));
        return arr.map(function (x, i) { return i });
    }

var sourceArray = fillArrayWithNumbers(1000);

Tests:

Push to new array
var targetArray = []; for (var i = 0; i < sourceArray.length; i = i+3) { targetArray.push(sourceArray[i]); };
Splice
for(var i = 0; i < sourceArray.length; i++) { sourceArray.splice(i+1,2); }
Filter
var targetArray = sourceArray.filter(function(_, i) { return (i % 3 == 0); })
