当时一位主要维护者甚至感慨道: Working through our (enormous) backlog of unsorted TypeScript "Suggestions" and it's remarkable how many of them are solved by conditional types. -- Ryan Cavanaugh 究竟是什么功能让这么多人孜孜以求呢?我们需要从一个实际案例讲起: functionprocess(text:string|null):s...
Check out 👉 Type-Level TypeScript, an online course teaching you how to unleash the full potential of TypeScript's Turing-complete type system. You already know how to code, and types are simply another programming language to master. This course bridges the gap, helping you apply your ex...
The Tarpit Law of Programming: "Every configuration language that supports logic, eventually evolves into an ad-hoc, informally-specified, bug-ridden, and slow implementation of a Turing-complete language."This is meant to be tongue-in-cheek: many of the above languages are well-specified, and...
Prefer types that only represent valid states. Even if they are longer or harder to express, they will save you time and pain in the end! Item 29: Be Liberal in What You Accept and Strict in What You Produce Thisidea is known as therobustness principleorPostel’s Law, after Jon Postel...
We have the ability to describe any computation using these abilities (the type system is turing complete). Conclusion If you are able to think of TypeScript as being a very expressive way to operate over sets, and using those sets to enforce strict compile time checks, you will most likely...
They enable you to create functions, classes, or interfaces that can work with different types while still providing the benefits of static typing. Here's an example using generics in a TypeScript function: The generic function identity allows you to work with different types without losing type...
The TypeScript Handbook is a comprehensive guide to the TypeScript language. It covers basic types, variable declarations, interfaces, classes, functions, generics, enums, type inference, type compatibility. Later sections examine advanced types, symbols, iterators and generators, modules, namespaces, ...
