Emacs, Advanced text editor, Quick Start
Emacs is a popular advanced text editor.
It’s a legacy technology, but it’s still being updated, making it a coding tool that goes beyond text editors.
A text editor is SW that can edit text. It is also used for coding.
IDE is a tool that has all the functions required for programming, including an editor.
However, recent text editors have been expanded in functionality and the difference from IDEs is becoming smaller.
