The JavaScript Bits You Skipped the First Time Around

Being humans, we rarely learn things linearly. No one begins their JavaScript journey by reading the TC39 language specification line-by-line like a pedantic masochist.

Instead we all cobble together a good-enough understanding, leaving holes here and there to fill in later.

So far I've stumbled along without 100% grokking prototypical inheritance, or how call, apply, and bind work on functions.
It's fine. Stuff mostly works. Until it doesn't ¯_(ツ)_/¯

But at some point, it's useful to stop stumbling about and peek back at those holes.

Tyler Clark latest course on Advanced JavaScript Foundations is exactly that hole-filling opportunity.

Tyler runs through all the details that usually get skipped over in beginners tutorials. The ones that make a huge difference when you're deep in a debugging session, and can't figure out where the f🍪🍩k this is pointing and why all your results are undefined.

Here's some of my sketch notes from the course – they include plenty of DNA inheritence metaphors 🧬 and a few cups of caffiene to keep you alert.

Hopefully these gave you a sense of the main concepts, and a small map of where your own JavaScript 🕳 holes are (or lack of holes if you've already diligently filled them in!)
