Visual Studio Code includes built-in JavaScript IntelliSense, debugging, formatting, code navigation, refactorings, and many other advanced language features.

Most of these features just work out of the box, while some may require basic configuration to get the best experience. This page summarizes the JavaScript features that VS Code ships with. Extensions from the VS Code Marketplace can augment or change most of these built-in features. For a more in-depth guide on how these features work and can be configured, see Working with JavaScript.

IntelliSense shows you intelligent code completion, hover information, and signature information so that you can write code more quickly and correctly.

VS Code provides IntelliSense within your JavaScript projects; for many npm libraries such as React, lodash, and express; and for other platforms such as node, serverless, or IoT.

See Working with JavaScript for information about VS Code's JavaScript IntelliSense, how to configure it, and help troubleshooting common IntelliSense problems.

A jsconfig.json file defines a JavaScript project in VS Code. While jsconfig.json files are not required, you will want to create one in cases such as:

To define a basic JavaScript project, add a jsconfig.json at the root of your workspace:

See Working with JavaScript for more advanced jsconfig.json configuration.

VS Code includes basic JavaScript snippets that are suggested as you type;

There are many extensions that provide additional snippets, including snippets for popular frameworks such as Redux or Angular. You can even define your own snippets.

VS Code understands many standard JSDoc annotations, and uses these annotations to provide rich IntelliSense. You can optionally even use the type information from JSDoc comments to type check your JavaScript.

Quickly create JSDoc comments for functions by typing /** before the function declaration, and select the JSDoc comment snippet suggestion:

To disable JSDoc comment suggestions, set "javascript.suggest.completeJSDocs": false.

Hover over a JavaScript symbol to quickly see its type information and relevant documentation.

The ⌘K ⌘I (Windows, Linux Ctrl+K Ctrl+I) keyboard shortcut shows this hover information at the current cursor position.

As you write JavaScript function calls, VS Code shows information about the function signature and highlights the parameter that you are currently completing:

Signature help is shown automatically when you type a ( or , within a function call. Press ⇧⌘Space (Windows, Linux Ctrl+Shift+Space) to manually trigger signature help.

Automatic imports speed up coding by suggesting available variables throughout your project and its dependencies. When you select one of these suggestions, VS Code automatically adds an import for it to the top of the file.

Just start typing to see suggestions for all available JavaScript symbols in your current project. Auto import suggestions show where they will be imported from:

If you choose one of these auto import suggestions, VS Code adds an import for it.

In this example, VS Code adds an import for Button from material-ui to the top of the file:

To disable auto imports, set "javascript.suggest.autoImports" to false.

VS Code's built-in JavaScript formatter provides basic code formatting with reasonable defaults.

The javascript.format.* settings configure the built-in formatter. Or, if the built-in formatter is getting in the way, set "javascript.format.enable" to false to disable it.

For more specialized code formatting styles, try installing one of the JavaScript formatting extensions from the Marketplace.

All of VS Code's JavaScript features also work with JSX:

You can use JSX syntax in both normal *.js files and in *.jsx files.

VS Code also includes JSX-specific features such as autoclosing of JSX tags:

Set "javascript.autoClosingTags" to false to disable JSX tag closing.

Code navigation lets you quickly navigate JavaScript projects.

You can navigate via symbol search using the Go to Symbol commands from the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)).

Press F2 to rename the symbol under the cursor across your JavaScript project:

VS Code includes some handy refactorings for JavaScript such as Extract function and Extract constant. Just select the source code you'd like to extract and then click on the lightbulb in the gutter or press (⌘. (Windows, Linux Ctrl+.)) to see available refactorings.

Available refactorings include:

See Refactorings for more information about refactorings and how you can configure keyboard shortcuts for individual refactorings.

Unused JavaScript code, such the else block of an if statement that is always true or an unreferenced import, is faded out in the editor:

You can quickly remove this unused code by placing the cursor on it and triggering the Quick Fix command (⌘. (Windows, Linux Ctrl+.)) or clicking on the lightbulb.

To disable fading out of unused code, set "editor.showUnused" to false. You can also disable fading of unused code only in JavaScript by setting:

The Organize Imports Source Action sorts the imports in a JavaScript file and removes any unused imports:

You can run Organize Imports from the Source Action context menu or with the ⇧⌥O (Windows, Linux Shift+Alt+O) keyboard shortcut.

Organize imports can also be done automatically when you save a JavaScript file by setting:

The editor.codeActionsOnSave setting lets you configure a set of Code Actions that are run when a file is saved. For example, you can enable organize imports on save by setting:

You can also set editor.codeActionsOnSave to an array of Code Actions to execute in order.

Here are some source actions:

See Node.js/JavaScript for more information.

VS Code automatically suggests some common code simplifications such as converting a chain of .then calls on a promise to use async and await

Set "javascript.suggestionActions.enabled" to false to disable suggestions.

GitHub Copilot is an AI-powered code completion tool that helps you write code faster and smarter. You can use the GitHub Copilot extension in VS Code to generate code, or to learn from the code it generates.

GitHub Copilot provides suggestions for numerous languages and a wide variety of frameworks, and it works especially well for Python, JavaScript, TypeScript, Ruby, Go, C# and C++.

You can learn more about how to get started with Copilot in the Copilot documentation.

Once you have the Copilot extension installed and enabled, you can test it our for your JavaScript projects.

Create a new file - you can use the File: New File command in the Command Palette (F1).

In the JavaScript file, type the following function header:

Copilot will provide a suggestion like the following - use Tab to accept the suggestion:

Inlay hints add additional inline information to source code to help you understand what the code does.

Parameter name inlay hints show the names of parameters in function calls:

This can help you understand the meaning of each argument at a glance, which is especially helpful for functions that take Boolean flags or have parameters that are easy to mix up.

To enable parameter name hints, set javascript.inlayHints.parameterNames. There are three possible values:

Variable type inlay hints show the types of variables that don't have explicit type annotations.

Setting: javascript.inlayHints.variableTypes.enabled

Property type inlay hints show the type of class properties that don't have an explicit type annotation.

Setting: javascript.inlayHints.propertyDeclarationTypes.enabled

Parameter type hints show the types of implicitly typed parameters.

Setting: javascript.inlayHints.parameterTypes.enabled

Return type inlay hints show the return types of functions that don't have an explicit type annotation.

Setting: javascript.inlayHints.functionLikeReturnTypes.enabled

The JavaScript references CodeLens displays an inline count of reference for classes, methods, properties, and exported objects:

To enable the references CodeLens, set "javascript.referencesCodeLens.enabled" to true.

Click on the reference count to quickly browse a list of references:

When you move or rename a file that is imported by other files in your JavaScript project, VS Code can automatically update all import paths that reference the moved file:

The javascript.updateImportsOnFileMove.enabled setting controls this behavior. Valid settings values are:

Linters provides warnings for suspicious looking code. While VS Code does not include a built-in JavaScript linter, many JavaScript linter extensions available in the marketplace.

You can leverage some of TypeScript's advanced type checking and error reporting functionality in regular JavaScript files too. This is a great way to catch common programming mistakes. These type checks also enable some exciting Quick Fixes for JavaScript, including Add missing import and Add missing property.

TypeScript tried to infer types in .js files the same way it does in .ts files. When types cannot be inferred, they can be specified explicitly with JSDoc comments. You can read more about how TypeScript uses JSDoc for JavaScript type checking in Working with JavaScript.

Type checking of JavaScript is optional and opt-in. Existing JavaScript validation tools such as ESLint can be used alongside built-in type checking functionality.

VS Code comes with great debugging support for JavaScript. Set breakpoints, inspect objects, navigate the call stack, and execute code in the Debug Console. See the Debugging topic to learn more.

You can debug your client-side code using a browser debugger such as our built-in debugger for Edge and Chrome, or the Debugger for Firefox.

Debug Node.js in VS Code using the built-in debugger. Setup is easy and there is a Node.js debugging tutorial to help you.

VS Code ships with excellent support for JavaScript but you can additionally install debuggers, snippets, linters, and other JavaScript tools through extensions.

Read on to find out about:

VS Code supports JSX and React Native. You will get IntelliSense for React/JSX and React Native from automatically downloaded type declaration (typings) files from the npmjs type declaration file repository. Additionally, you can install the popular React Native extension from the Marketplace.

To enable ES6 import statements for React Native, you need to set the allowSyntheticDefaultImports compiler option to true. This tells the compiler to create synthetic default members and you get IntelliSense. React Native uses Babel behind the scenes to create the proper run-time code with default members. If you also want to do debugging of React Native code, you can install the React Native Extension.

Yes, there are VS Code extensions for both Dart and Flutter development. You can learn more at the Flutter.dev documentation.

Automatic Type Acquisition works for dependencies downloaded by npm (specified in package.json), Bower (specified in bower.json), and for many of the most common libraries listed in your folder structure (for example jquery-3.1.1.min.js).

ES6 Style imports are not working.

When you want to use ES6 style imports but some type declaration (typings) files do not yet use ES6 style exports, then set the TypeScript compiler option allowSyntheticDefaultImports to true.

Yes, you can. You can see this working using JavaScript source maps in the Node.js Debugging topic.

Some users want to use syntax constructs like the proposed pipeline (|>) operator. However, these are currently not supported by VS Code's JavaScript language service and are flagged as errors. For users who still want to use these future features, we provide the javascript.validate.enable setting.

With javascript.validate.enable: false, you disable all built-in syntax checking. If you do this, we recommend that you use a linter like ESLint to validate your source code.

Yes, but some of Flow's language features such as type and error checking may interfere with VS Code's built-in JavaScript support. To learn how to disable VS Code's built-in JavaScript support, see Disable JavaScript support.

Originally Answered: Why did Mark Zuckerberg force Eduardo Saverin out of Facebook?
