Javascript

Definitions

Node - asynchronous event driven JavaScript server-side runtime (javascript outside of the browser)

NPM vs Yarn - both package managers for Node, npm is the one built in, yarn is the one that is facebook open source.

Grunt vs Gulp vs Webpack - both are tas runners, automating basic tasks in web dev. ie processing sass files. Webpack bundles a bunch of stuff into a few final files. Then all the modules that depend on each other it'll help package it all up into static assets. Also has a little task runner included. Webpack has become WAY more popular.

Packages

budo - could help with rapid development. Nadieh Bremer uses it for live refresh I think
rough.js - make graphics with a sketch appearance, which looks really nice! and custom!
