VI/VIM editor and vivim Editor

VI/VIM editor and vivim Editor
1 Overview

All Unix Like systems have built-in vi file editors, while other file editors do not necessarily exist. However, we currently use the vim editor.

Vim has the ability to edit programs. It can actively identify the correctness of the syntax in the font color to facilitate program design. Vim is a text editor developed from vi. Code Completion, compilation, error jump, and other convenient programming functions are particularly rich and widely used by programmers.

To put it simply, vi is an old-fashioned word processor, but its functions are quite complete, but there is still something that can be improved. Vim is a useful tool for program developers. Even vim's official website (http://www.vim.org) itself says vim is a programming tool rather than a text processing software.
