A conditional type in TypeScript is an if-then-else expression: Its result is either one of two branches – which one depends on a condition. That is especially useful in generic types. Conditional types are also an essential tool for working with union types because they let us “loop” over them. Read on if you want to know how all of that works.| 2ality.com
In this blog post, we look at the special TypeScript type never which, roughly, is the type of things that never happen. As we’ll see, it has a surprising number of applications.| 2ality.com
In this blog post, we explore how we can extract parts of compound types via the infer keyword. It helps if you are loosely familiar with conditional types. You can check out chapter “Conditional types” in “Exploring TypeScript” to read up on them.| 2ality.com
