1Password is a popular password management tool that relies upon a browser extension to fill out passwords on the Web. At over a minute for a single build, things were starting to drag for the devs. Could esbuild help? A fun story with plenty of technical details.

Might come in handy for learning regular expressions or if you have a complex regular expression and you don’t know what it does (not an uncommon situation..!)

We linked to Martin's array of creative JavaScript experiments earlier, but why not finish with one that particularly tickled us? A quine is a program that takes no input but manages to produce, as output, its own source code. Here’s a fun JavaScript example that isn’t merely a quine, but a clock too.
