Benchmark: Lodash reduce vs Lodash Each

HTML Preparation code:

Script Preparation code:

var xpath = "/a/b1/c1/d1/../../../b2/c2/d2"
var xpathParts = xpath.split("/");

Tests:

Reduce (cloning)
_.reduce(_.clone(xpathParts), function(acc, node) { if (node === "..") { acc.pop(); } else { acc.push(node); } return acc; }, []);
Reduce (without cloning)
_.reduce(xpathParts, function(acc, node) { if (node === "..") { acc.pop(); } else { acc.push(node); } return acc; }, []);
Each (cloning)
var resultXPath = []; _.each(_.clone(xpathParts), function(xpathPart) { if (xpathPart === "..") { resultXPath.pop(); } else { resultXPath.push(xpathPart); } });
Each (without cloning)
var resultXPath = []; _.each(xpathParts, function(xpathPart) { if (xpathPart === "..") { resultXPath.pop(); } else { resultXPath.push(xpathPart); } });
