Selecting the snippet with tab results in: VS Code has several built-in snippets that will come up as you type or you can press kb() (Trigger Suggest) and you will see a context specific list of suggestions. IntelliSense is automatically provided for CommonJS and AMD modules inside your project folders. The typings are easily managed using TSD, the TypeScript Definition manager. DefinitelyTyped is a repository of typings files for all major JavaScript libraries and environments. VS Code provides IntelliSense for built-in symbols of browsers, Node.js, and virtually all other environments through the use of type definition. d.ts files, it’s a faster but less powerful way to define variables to be used inside source files.

When a "files" property is specified, only those files are included. Tip: Just as in tsconfig.json, if no "files" property is present, we default to including all files in the containing directory and subdirectories. The file itself lists the files belonging to the project as well as compiler options. ![]() The presence of a jsconfig.json file in a directory indicates that the directory is the root of a JavaScript project. You can create a JavaScript project by dropping in a jsconfig.json file. Peek, Go to Definition, Find all References, and Rename Symbol just by right clicking in any JavaScript file.
