Emmet is a popular plugin available for multiple IDEs including VSCode.

By Default it works when you are on .html file.

You can also make it work on .js files when working with JSX.

Open Settings in VSCode:

Ctrl + ,

Navigate to Workspace tab > Extensions

Untitled

Use “Edit in settings.json"

Add following config to the settings.json file:

{
   "emmet.includeLanguages": {
      "javascript": "javascriptreact"
   }
}

Untitled

Emmet should start working in .js files now.
