Benchmark: Split vs Regex vs Replace Iteration

Script Preparation code:

var testString = new Array(1000).fill(0).map(() => Math.random().toFixed(4)).join("\n");

Tests:

Splitting
testString.split("\n").forEach(v => { const f = parseFloat(v); if (!window.screen) console.log(f); });
Regex
var regex = /([^\n]+)\n/g while (true) { const match = regex.exec(testString); if (!match) break; const f = parseFloat(match[1]); if (!window.screen) console.log(f); }
Replace
testString.replace(/[\-0-9.]/g, v => { const f = parseFloat(v); if (!window.screen) console.log(f); return ""; });
