Is there a package that helps me benchmark JavaScript code? I'm not referring to Firebug and such tools.  I need to compare 2 different JavaScript functions that I have implemented. I'm very familiar with Perl's Benchmark (Benchmark.pm)...
Between Yahoo! UI Compressor, Dean Edwards Packer and jsmin, which produces better results, both in terms of resulting footprint and fewer errors when obfuscating....
Today I visited jsPerf and now I am wondering…   What is “ops/sec”? How many iterations does it do? On what basis does it calculate which is faster? What is the formula behind these calculations?   Example: http://jsperf.com/concatenation-vs-jo...
I pretty don't understand why this test :  http://jsperf.com/push-method-vs-setting-via-key  Shows that    a.push(Math.random());   is over ten times slower than    a[i] = Math.random();   Could you explain why this is the case ? What magic "...
I ran a test on this website  http://jsperf.com/    I want some one to explain   What does green and pink signifies What is ops per second what is 95,814,583 what is +- 1.95% is whats does 'fastest' and 'slower' means...

I was messing around with the benchmark site jfprefs and created my own benchmark at http://jsperf.com/prefix-or-postfix-increment/9.  The benchmarks are variations of Javascript for loops, using prefix and postfix incrementors and the Crockford jsli...
I would like to calculate how long an async function (async/await) is taking in JavaScript.  One could do:  const asyncFunc = async function () {};  const before = Date.now(); asyncFunc().then(() => {   const after = Date.now();   console.log(afte...
I often see arguments between Classical (faked via some library), Pseudo-Classical and Prototypal Inheritance mention "efficiency." However, I've never seen any data backing any of this kind of stuff up. Not to mention "efficiency"...
tl;dr version:   Is there a benchmark or syntax examples of when (if ever) to use c++ instead of JS in Qt 5.7 and/or to define the performance of JS vs. c++ in Qt 5.7 confirming the latter is indeed faster as the Documentation for the project states...
