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...

Typescript allows you to configure the compiler, thus giving you more fine-grained control over writing code. You can set the version of the ECMA script and error priorities by adjusting its strict mode. Their configurations are done in atsconfig.jsonfound at the root of the project. You can...
While these two terms are often used interchangeably amongst developers, there is a subtle difference between type assertion and type casting in TypeScript: Type assertion: This is a way for you to tell the TypeScript compiler to treat an entity as a different type than it was inferred to be...
you have types for some of your packages working and your own code checked by the TypeScript compiler. The next step is to fix compile errors in the rest of the package types, or to fix them in your own code. Or you can just ignore the errors and start using the TypeScript support...
