The heart of every developers toolchain is the editor. As your editor is the heart of your environment, you should be aware about its capabilities.
You can choose, what ever you like.
When you are developing a java or .net based system, you may be better of using a full blown IDE.
But this is not neccessary every time.
I want to show you, how far you can get, using
vim as you primary editor.
You can find
vim on almost every system out there.
Over the last decades a wide ecosystem has emerged.
You can extend
vim with serveral
plugins
to get a more IDE like editor.
