JS terminology

• "primitive": boolean, number, string, symbol, null, undefined
• "object" aka "non-primitive": any "custom object" (e.g. { foo: 1 }) or function

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#Data_types

(In JS, people mistakingly think of primitives as "object"s, but in strict JS terminology, they're not.)

<script> async, defer, async defer, module, nomodule, src, inline - the cheat sheet

With the addition of ES modules, there's now no fewer than 24 ways to load your JS code: (inline|not inline) x (defer|no defer) x (async|no async) x (type=text/javascript | type=module | nomodule) -- and each of them is subtly different.

This document is a comparison of various ways the <script> tags in HTML are processed depending on the attributes set.

If you ever wondered when to use inline <script async type="module"> and when <script nomodule defer src="...">, you're in the good place!

Note that this article is about <script>s inserted in the HTML; the behavior of <script>s inserted at runtime is slightly different - see Deep dive into the murky waters of script loading by Jake Archibald (2013)

A guide to writing a language grammar (TextMate) in Atom

Tree sitter

• Atom is transitioning to an entirely new way of defining grammars using tree-sitter. This will be enabled by default quite soon now. It is theoretically faster and more powerful than regex based grammars (the one described in this guide), but requires a steeper learning curve. My understanding is that regex based grammars will still be supported however (at least until version 2), so this guide can still be useful. To enable it yourself, go to Settings -> Core and check Use Tree Sitter Parsers

Links for tree-sitter help:

• tree-sitter: the main repo
• tree-sitter-cli: converts a JavaScript grammar to the required C/C++ files
• node-tree-sitter: module to use Tree-sitter parsers in NodeJS
• [My guide on starting a Tree-sitter grammar
