Benchmark: Reduce vs map/join 100

Script Preparation code:

var strings = {};
for (var i=0; i<100; i++) {
  strings[i] = ""+i+i;
}

Tests:

for
var result = ""; var keys = Object.keys(strings); for (var i in keys) { result += ' '+i+strings[i]; }
reduce
var result = Object.keys(strings).reduce(function(string, i) { return string+' '+i+strings[i]; }, "");
map
var result = Object.keys(strings).map(function(i) { return i+strings[i]; }).join(' ');
