Micro-benchmarking JavaScript tips

Why the JavaScript engine will mislead the micro-benchmarking you carefully crafted


Often micro-benchmarks are used to decide a feature is slower or faster than another.

Here I will debunk some micro-benchmarks by explaining what happens internally in the Javascript engine, together with formulating advice on how to properly benchmark features.
