Todo lists are boring and pretty limited so in this video I am going to show you how to build a more advanced project that covers all the features of a todo list while also adding tons of additional features like categories, markdown support, filter, etc. This is a great intermediate to advanced project.

The Perfect Advanced React/TypeScript Project - Markdown Supported Note Taking With Categories

TypeScript's infer keyword is MUCH narrower, much less widely used than you think it is. It has ONE use case, and we cover it in a ridiculous amount of depth here.

Infer is easier than you think

Don't fall for it!

The Zen of Python must not have been invented yet because this feature is confusing, not obvious, implicit, and much more. Private name mangling in Python converts variable usages like __var into _ClassName__var at compile time and there's no warning it's happening until you run into the trap.

Every Python dev falls for this (name mangling)

Get rid of recursion with this trick!

Recursion is great, an extremely useful tool to have a mastery of. However, recursion is limited by the depth of the allowed call-stack before an error is caused. Sometimes, depth is not a problem. But other times, it is better to convert your recursive algorithm into an iterative one by manually managing your own stack, which is what we'll see in this Python video.
