Vim Editor | Why do I need it ?

Vim is the editor of choice for many developers and power users. It’s a “modal” text editor based on the vi editor written by Bill Joy in the 1970s for a version of UNIX. It inherits the key bindings of vi, but also adds a great deal of functionality and extensibility that are missing from the original vi.
