A note to self lest I forget the resources I learned from.


As I was going thru Swyx's React TypeScript Cheatsheet, Props: Omit prop from a type, I had trouble understand the definition of Omit.

Could not wrap my heads around it so Googled and found Marius Schulz's blog posts.

Blog read order

I read these backwards initially but the posts in following order seems to make sense.

  1. keyof and Lookup Types in TypeScript - Learn about keyof used for Omit and Exclude
  2. Conditional Types in TypeScript - To understand Exclude
  3. The Omit Helper Type in TypeScript - To finally learn how Omit is implemented
