How to set per-filetype tab size in VS Code?

Setting the tab size for each file type in Visual Studio Code can be achieved by configuring it in the workspace settings. The following steps outline the process:

1. Open Settings: Launch VS Code, then click the gear icon in the bottom-left corner and choose 'Settings' (or press Ctrl + , to open the settings).

2. Search for 'Tab Size': Enter 'Tab Size' in the settings search bar to view related options.

3. Modify Global Settings: In the search results, adjust the value for 'Editor: Tab Size' to set the default tab size for all file types.

4. Set for Specific File Types: To configure different tab sizes for specific file types, edit the settings.json file. Click the '{ }' icon in the top-right corner to open Settings (JSON) for direct editing.

   In settings.json, you can add configurations like the following:

   json
   "[javascript]": {
       "editor.tabSize": 2
   },
   "[python]": {
       "editor.tabSize": 4
   }

   This configuration sets the tab size for JavaScript files to 2 and for Python files to 4.

5. Save and Apply Settings: Save the settings.json file. VS Code will automatically apply the new settings.

By following these steps, you can set specific tab sizes for different file types to match various programming language conventions and team standards. This method is particularly useful for maintaining clean and consistent code in multi-language projects.
