Non-performant JS Patterns

gistfile1.md

It pains me to write this, because I prefer the more robust, function-composition-focused features of Javascript, but there's a threshold of performance where speed overrides elegance. After all, performance is half the reason that programming is skilled labor. So here we have it-- my list of performance benchmarks and advice.

The Unusable

Try / Catch -- Use conditionals instead

Try/Catch Performance may be pitting try/catch against an easy-to-optimize opponent, but it still makes a strong case.

Function Bind -- Use closure variables instead

Bind's Performance is pretty ugly. It hurts me to say that bind should only be used in the most extreme cases.

The First-To-Replace

.forEach/.map -- Replace with traditional loops

Loop vs map vs forEach shows ~7x difference; real, but not worrisome.
