TypeScript 编译器(tsc)的主要功能是将 TypeScript 代码(.ts 文件)编译成 JavaScript 代码(.js 文件)。这个过程包括类型检查、代码转换以及生成符合 ECMAScript 标准的 JavaScript 代码。TypeScript 编译器还允许开发者通过配置文件(如 tsconfig.json)来自定义编译过程,包括指定目标 JavaScript 版本、模块系统、是否生成...
When it comes to classes, TypeScript’s analysis can flag properties that aren’t definitively initialized, and this can save you some pain. It can alsocausesome pain if the framework you’re using is guaranteed to set those properties before your code will run. While you can set these pro...

Two steps are exclusive to TypeScript, binder and checker. We are going to gloss over checker as it relates to TypeScripts type checking specifics.For a more in-depth understanding of the TypeScript compiler internals have a read of Basarat's handbook....
