VS Code’s built-in JavaScript formatter provides basic code formatting with reasonable defaults. 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. Hover over a JavaScript symbol to quickly see its type information and relevant documentation. 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.

  • Node.js has also made it possible to use JavaScript in backend development with its frameworks like Express.js.
  • Folding regions are available for all HTML elements for multiline comments in the source code.
  • Once you have the Copilot extension installed and enabled, you can test it our for your JavaScript projects.
  • The source map helps the debugger figure out how to map between your original code, and the code running in the browser.

It supports configuration of hue, saturation and opacity for the color that is picked up from the editor. It also provides the ability to trigger between different color modes by clicking on the color string at the top of the picker. The picker appears on a hover when you are over a color definition.

Before using your text editor, it’s important to establish an organized file system. As the number and size of your projects grow, it becomes increasingly important to know where to save new projects and find old projects. In these cases, VS Code’s IntelliSense will operate in partial mode. Partial mode tries its best to provide IntelliSense for any JavaScript or TypeScript files you have open, but is limited and is not able to offer any cross-file IntelliSense features. Once you have added this, you can start Babel with the ⇧⌘B (Windows, Linux Ctrl+Shift+B) (Run Build Task) command and it will compile all files from the src directory into the lib directory.

You can read more about using custom data in the vscode-custom-data repository. You can fold regions of source code using the folding icons on the gutter between line numbers and line start. Folding regions are available for all HTML elements for multiline comments in the source code.
