Question: If a newcomer to JavaScript asked you for essential libraries and tools, what would you tell them? You don’t want to overwhelm them with too many suggestions!

Focus: language-related functionality (as opposed to browser-related functionality).

• Libraries: including, say, Underscore.js and promises libraries, but excluding jQuery et al.
• Tools: package managers, build tools, unit test tools, etc.
  • Less important: editors, IDEs. Rationale: it’s fairly obvious that you need them. There are other tools that people might not even know that they need.

// If exec() is invoked on a regular expression whose flag /g is set
// then the regular expression is abused as an iterator:
// Its property `lastIndex` tracks how far along the iteration is
// and must be reset. It also means that the regular expression can’t be frozen.
