TypeScript 的构建方式有很多种,除了原生编译器tsc 以外,还包括 Webpack、Rollup、Babel 以及 Gulp 等(更多构建工具的集成可查看Integrating with Build Tools[32]): Webpack 主要用于页面应用的模块化构建,使用 Webpack 构建会增加构建库的体积,因此简单工具库的制作使用 Webpack 完全是 "杀鸡用牛刀"。 Rollup 是...
TypeScript编译器已经禁止了许多此类操作。然而,有些操作还是有可能绕过编译器的,例如,使用as any转换对象的类型,或者在编译TS代码时关闭严格类型检查的配置,或者在代码中通过@ts-ignore忽略类型检查。 在ArkTS中,严格类型检查不是可配置项。ArkTS强制进行部分严格类型检查,并通过规范禁止使用any类型,禁止在代码中使用@...
For example, we can write a type with an index signature that takes string keys and maps to boolean values. If we try to assign anything other than a boolean value, we’ll get an error. Copy interface BooleanDictionary { [key: string]: boolean; } declare let myDict: BooleanDictionary;...

TypeScript has a concept calledindex signatures. Index signatures are part of a type, and tell the type system what the result of an element access should be. For instance, in the following: Copy interfaceFoo{// Here is a string index signature:[prop:string]:boolean; ...
For example, we can write a type with an index signature that acceptsstringkeys and maps tobooleanvalues. If we try to assign anything other than abooleanvalue, we’ll get an error. Copy interfaceBooleanDictionary{[key:string]:boolean;}declareletmyDict:BooleanDictionary;// Valid to assign boo...
For example, if an implementation package.json looks like: { "name": "my-package", "version": "1.0.1", "type": "module", "main": "dist/cjs/index.cjs", "exports": { ".": { "import": "./dist/esm/index.js", "require": "./dist/cjs/index.cjs" }, "./subpath": { "...
