A Small HTM VM FTW OMG BBQ

This is a half-baked sketch of compiling HTM expressions into a list of instructions that can be interpreted in runtime with a compact function. The instructions hopefully compress well and the evaluation function should be not-slow. Maybe.

• evaluate.js contains the evaluation function (evaluate(...)) as well as an example of a compiled HTM call.

• babel.js contains a Babel plugin that transforms HTM calls into the stack language. The build.mjs file it imports is HTM's src/build.mjs.

This tweet demonstrates that a minified evaluate() fits in one tweet: https://twitter.com/jviide/status/1257755526722662405 🙂

It is a melancholy object-oriented language to those who walk through
this great town or travel in the country, when they see the JavaScript
programs crowded with method calls begging for more succinct syntax.
I think it is agreed by all parties, that whoever could find out a
fair, cheap and easy method of making these operators sound and useful
members of the language, would deserve so well of the publick, as
to have his statue set up for a preserver of the nation. I do therefore
humbly offer to publick consideration a pure JS library I've written
for overloading operators, which permits computations like these:

<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)

Samples.js: a tiny and simple Web Audio API based sample playback library

Web Audio API spec is a great way of professional audio playing and mixing in the modern browser. However, it's too complex and versatile for some simple one-off tasks such as "load an audio sample into memory and just play it when necessary". That's why Samples.js has come true. It's a really simple and tiny (less than 1K minified) library that exposes just 5 methods to manipulate your samples from JS code in a really easy and fun way.

API reference

The library exposes the following calls:
