The TypeScript compiler only uses TypeScript type annotations and ignores those from JSDoc. Keep in mind that when using JSDoc for TypeScript code, you should not include type annotations. VS Code's TypeScript IntelliSense understands many standard JSDoc annotations, and uses them to show typing information and documentation in suggestions, hover info, and signature help. If you'd like to see snippets, you can specify the order relative to suggestions at the top ( "top"), at the bottom ( "bottom"), or inlined ordered alphabetically ( "inline"). Tip: You can disable snippets by setting editor.snippetSuggestions to "none" in your settings file. See User Defined Snippets for more information.

You can install extensions to get additional snippets or define your own snippets for TypeScript.

VS Code includes basic TypeScript snippets that are suggested as you type VS Code provides IntelliSense for individual TypeScript files as well as TypeScript tsconfig.json projects. Sorry, your browser doesn't support HTML 5 video. IntelliSense shows you intelligent code completion, hover info, and signature information so that you can write code more quickly and correctly.
Whether the variable/property type is callable (a function type) or not. Whether the variable/property is read-only (const) or modifiable. The resolved type of a symbol: namespace, variable, property, variable, property, class, interface, typeParameter. Semantic highlighting can change colors based on: If semantic highlighting is enabled and the color theme has a corresponding styling rule defined, different colors and styles can be seen. Each theme can configure whether to display semantic highlighting and how it styles the semantic tokens. Whether semantic highlighting is visible depends on the current color theme. Semantic highlighting enriches the syntax coloring based on resolved symbol information from the language service. Syntax highlighting colors the text based on lexical rules. In addition to syntax highlighting, TypeScript and JavaScript also provide semantic highlighting. Syntax highlighting and semantic highlighting tsc -versionĪnother option is to install the TypeScript compiler locally in your project ( npm install -save-dev typescript) and has the benefit of avoiding possible interactions with other TypeScript projects you may have. You can test your install by checking the version. If you have npm installed, you can install TypeScript globally ( -g) on your computer by: npm install -g typescript The easiest way to install TypeScript is through npm, the Node.js Package Manager. You will need to install the TypeScript compiler either globally or in your workspace to transpile TypeScript source code to JavaScript ( tsc HelloWorld.ts). Visual Studio Code includes TypeScript language support but does not include the TypeScript compiler, tsc. It offers classes, modules, and interfaces to help you build robust components. TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. Configure IntelliSense for cross-compiling.
