Spacemacs' layer for javascript is a good starting reference:

https://github.com/syl20bnr/spacemacs/blob/master/layers/%2Blang/javascript/packages.el#L12

While there may be some small overlap between js2-mode and flycheck
you'll most likely want them both: js2-mode gives you font lock and
indentation and potentially some syntax checking, but flycheck can hook
into a wide array of external tools that go beyond what js2-mode
provides.

Tern + company-tern appears to be the way to go for semantic
autocompletion, unless you're using Flow or Typescript in which case
those can also provide completion via their packages.
