NERDTree will give you file hierarchy, CoC will give you insane-levels of autocomplete that rival or beat intellisense and you can use keybindings to navigate directly to method definitions, typings, anything.

Claiming the terminal doesn't do these things demonstrates the lack of time invested time to learn or discover what's available. Again to each their own, but it seems to be the author claims there are no good editors when they simply are just too eager to "open up vscode".

Oh, I have vim with tons of plugins and use gvim for simpler discovery of some features I les softne use, thus know that vim isn't strictly bound to the terminal.

But there is a massive difference while browsing code between the IntelliJ style editor and all the vim plugins in the world.
