本文探讨了TypeScript中适当使用类型的重要性，强调避免使用Number、String等类型，转而推荐使用number、string等原始类型。文章还介绍了如何正确地利用非原始对象类型，以提升代码质量和类型安全性。

Typescript Do's and Don'ts

// Don’t ever use the types Number, String, Boolean, Symbol, or Object These types refer to non-primitive boxed objects that are almost never used appropriately in JavaScript code.
function reverse(s: String): String {}

// Do use the types number, string, boolean, and symbol.
function reverse(s: string): string {}

// Instead of Object, use the non-primitive object type (added in TypeScript 2.2).
