Benchmark: Loop Test - MeasureThat.net

Script Preparation code:

var xs = [];
for( var x = 0; x < 1000000; x++ ) xs[x] = x;

Tests:

Imperative
var count = 0; var sum = 0; xs.forEach(function(x){ count = count + 1; sum = sum + x; });
Multiple reduces
var totalSum = xs.reduce(function(x,y){ return x + y }); var totalCount = xs.reduce(function(n, _){ return n + 1 });
Single reduce
var initialState = { count: 0, sum: 0 } function step( state, n ){ return { count: state.count + 1, sum: state.sum + n } } var results = xs.reduce( step, initialState );
