Ganesh Khade What do you recommend, Vim, Sublime Text or VS Code for a newbie? I used to recommed VS Code, but everyone I recommend complained about, how slow it was than Sublime Text.

Ice I think it's definitely worth learning vim just for the key bindings. It speeds up your workflow so much once you're past the learning curve, and most editors (e.g. Sublime, VSCode, Jetbrains) support vim bindings out-of-the-box or with an official plugin.
