1. TypeScript 编译器的功能 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 JavaSc...
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...
To help you quickly get started with a new TypeScript project, WebStorm offers a built-in TypeScript compiler that you can use instead of configuring some other build tool. Let’s have a closer look at it! Once you open a TypeScript file, WebStorm will suggest enabling its built-in Typ...
Typescript offers numerous advantages, such as autocomplete code suggestions, highlighting errors at compile-time, and simplifying the debugging process, to name a few. It compiles to JavaScript and also compiles vanilla JavaScript, providing a gradual learning curve for developers. This guide ...
An intro to number-based enums When do we need string-based enums? Constant and computed enums Specifying enum member values String literals and union types Use cases and the importance of string-based enums Comparing number- and string-based enums Enums at runtime and compile time...

Check the Interface Type on Runtime in TypeScript This article discusses how to check the object type on runtime in TypeScript. ADVERTISEMENT Main Types in TypeScript TypeScript is a strongly typed language. Therefore, it checks for the types in compile time, which reduces runtime errors. ...
go run hello.goOur program ran successfully, and it printed “Hello, World!” to the terminal!The go run tool first compiles and then runs the program specified.You can create a binary using go build:go build hello.goThis will create a hello file that’s a binary you can execute:...
Loaders such aswebpackuse a mapping configuration to map the module name (in this case,express) to theindex.jsfile at runtime, thereby translating the snippet above tonode_modules/express/lib/expressat runtime. At this point, when we use the translated snippet above in a TypeScript project...
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 suppor...
