I just installed Visual Studio Code. It works and suggests HTML and stylesheet and JavaScript as well, but what matters is that I didn't install any extension in Visual Studio Code, and it works well without HTML and JavaScript extension.
How does it work without any extension? Do I need to install an extension for this?
To answer it on Low-Level, VS Code is built on top of monaco-editor
As mentioned in its docs, it has below stuffs by default
Rich IntelliSense, Validation TypeScript, JavaScript, CSS, LESS, SCSS, JSON, HTML
Refer: https://microsoft.github.io/monaco-editor/
Those shortcut features are built with https://emmet.io/
So, for working with basic web stuffs, you don't need an extension.
