Mapped type MODIFIERS in TypeScript - Advanced TypeScript

Показать описание
In a previous TypeScript tutorial we've looked at mapped types and looked at how we can generate a new type where all the members can be marked as readonly. Now readonly in that case is a type modifier. In this lesson we will look at additional type modifiers supported by TypeScript mapped types,

We also cover a real world use case and deploy the built in Partial type function provided by TypeScript 🌹

This is incredibly clear, and your real-world example was fantastic!

At first I was wondering how plus sign helps. I even considered it more noise rather than helping in "readability". Then I saw the minus sign. Mind blown!

Your videos keep blowing my mind, especially for typescript. Love it!
