Use Visual Studio Code in the Browser

How great is that? Now we can use VS Code in the Browser by navigating to It´s possible to create and edit documents in GitHub repositories as well as working with local files.

You can create a new file in the web just as you would in a desktop VS Code environment, using File > New File from the Command Palette (F1).

See the announcement. There are limitations. You wouldn´t have a Terminal window, for example, but editing something on your blog just inside your GitHub repository works much better now.
