inline SourceMap会包含在生成的js文件中 "declarationMap": true, // 为声明文件生成sourceMap "typeRoots": [], // 声明文件目录,默认时node_modules/@types "types": [], // 加载的声明文件包 "removeComments":true, // 删除注释 "noEmit": true, // 不输出文件,即编译后不会生成任何js文件 "...
console.log( arr.map( function( item, index, array ){ console.log(item);returnitem >3; })); 打印出来的结果是:1,2,3,4,5,6函数返回结果: [false,false,false,true,true,true] filter 同样返回一个新的数组,但是返回的是符合条件的数组项,同样不会跳出循环 vararr = [1,2,3,4,5,6]; con...

this would complicate our build process, make stack trace analysis harder, and force us to ship with source maps (or find a source map host, kind of like what asymbol serverdoes for debug information).

16、什么是 .map 文件,为什么/如何使用它? 甲.map文件是源地图,显示原始打字稿代码是如何解释成可用的JavaScript代码。它们有助于简化调试,因为你可以捕获任何奇怪的编译器行为。 调试工具还可以使用这些文件来允许你编辑底层的 TypeScript 而不是发出的 JavaScript 文件。
forceConsistentCasingInFileNames设置文件名是否为大小写敏感,默认为true。 17. incremental incremental让 TypeScript 项目构建时产生文件tsbuildinfo,从而完成增量构建。 18. inlineSourceMap inlineSourceMap设置将 SourceMap 文件写入编译后的 JS 文件中,否则会单独生成一个.js.map文件。
Map.groupByis similar, but produces aMapinstead of a plain object. This might be more desirable if you need the guarantees ofMaps, you’re dealing with APIs that expectMaps, or you need to use any kind of key for grouping – not just keys that can be used as property names in JavaScri...
It will prompt you to select the desired language, then you can find the generated challenges in the./playgroundfolder. Later if you want to update playground while keeping your changes: OR pnpm generate -K This project was born from solving real-world types problem with@hardfistand@MeCKodo....
Exception: new Map<string, number>() is OK. Using the types Function and Object is almost never a good idea. In 99% of cases it's possible to specify a more specific type. Examples are (x: number) => number for functions and { x: number, y: number } for objects. If there is...
