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
In some cases, the JavaScript code might not be processed as a valid code by the TypeScript compiler. It is due to the compile-time type checking feature in TypeScript language. It avoids most runtime errors that occur due to the wrong usage of types. As we all know, browsers are capa...
