I'm sorry but I still prefer sublime text, and it finally fixed syntax folding! Sublime text also has a cheap way to do auto-completion, it will just look at existing words in the current file, it's often just enough.
Vscode like many text editors supports that kind of completion too, but you should seriously give a try to better completion engines such as GitHub Copilot or StarCoder.
Just installing the proper LSP for the language you work in makes a world of difference.
