IntelliSense for JavaScript libraries and frameworks is powered by TypeScript type declaration (typings) files.

In addition to objects, methods, and properties, the JavaScript IntelliSense window also provides basic word completion for the symbols in your file.

This document describes the JSDoc annotations currently supported. When type inference does not provide the desired information, type information may be provided explicitly with JSDoc annotations. While IntelliSense should just work for most JavaScript projects without any configuration, you can make IntelliSense even more useful with JSDoc or by configuring a jsconfig.json project.įor the details of how JavaScript IntelliSense works, including being based on type inference, JSDoc annotations, TypeScript declarations, and mixing JavaScript and TypeScript projects, see the JavaScript language service documentation. Our JavaScript IntelliSense is powered by the JavaScript language service developed by the TypeScript team. Visual Studio Code's JavaScript IntelliSense provides intelligent code completion, parameter info, references search, and many other advanced language features. Using the TypeScript language service, VS Code can provide smart completions (IntelliSense) as well as type checking for JavaScript.

This topic describes some of the advanced JavaScript features supported by Visual Studio Code. Configure IntelliSense for cross-compiling.
