JavaScript

Specification

The words MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL are interpreted as described in RFC 2119.

Clarity is the highest JavaScript virtue. If your code requires a comment to explain its control flow, rewrite it.

JavaScript rewards explicit, readable code. You SHOULD prefer boring patterns that are easy to understand over clever tricks that save characters.
