Mapped Types in TypeScript
How well do you know unions in TypeScript? Join me in this episode to discover everything you need to know about unions in TypeScript. We will talk about what a union really is, the syntax, and under which circumstances it could be useful. I will show you how to use literal types to create more advanced definitions for your types. We will learn the concept of discriminated unions, and I will show some practical examples to get the most out of them.
