Emulating Xmonad in JavaScript - Part 3

Look! I made more progress!

This week has mostly been bug-fixing and reverse-engineering the functionality of certain control sequences.

One method I've found very useful is opening and running

 $ printf '\e#8'   # fill the terminal screen with "E" (no really)
 $ printf '\e[XXX'

to see what happens!

I'm slowly starting to realise (a) how complicated terminals are, (b) how tricky ANSI control sequences are as an API and (c) that I'm trying to write an ASNI-compliant terminal in Node.js...

This week's post is a short one, and I'll make sure to post another one ASAP.

🚀⚙️ JavaScript Visualized: the JavaScript Engine

As JavaScript devs, we usually don't have to deal with compilers ourselves. However, it's definitely good to know the basics of the JavaScript engine and see how it handles our human-friendly JS code, and turns it into something machines understand! 🥳

Happy coding!
