So I have never thought the Roblox code editor is “slow”.
I am more of an advanced developer, and I know what framework Visual Studio Code was made with, and I know that it is just another ram sucking web browser that happens to be able to open code files.
What are the real benefits of using Visual Studio Code for Roblox? I obviously want git in the near future, but I hate Visual Studio Code because it’s a ram sucking web browser.
Thank you 
It’s more of whether you find it more comfortable in VSC or in Roblox Studio. Either works, VSC has more customisation but with roblox studio, you don’t need to hook anything up.
the benefits isn’t really for what the editor does, but rather the functionality it allows you to extend. you mentioned git, which is a massive reason to use an external editor, that is used alongside with rojo.
neither of these tools are tied to an IDE. both are terminal tools that you could use with any code editor of your preference. where the difference may come is in that since vs code is so mainstream, you are way more likely to find useful plugins/extensions that may complement your workflow. (linting, LSP’s, autofill, snippets, etc.)
i only really use vscode because i work with roblox-ts and most of the maintainers also use vscode (and maintain the plugins)
