An editor program, often called a text editor or code editor, is a software application used to create, modify, and save text files. It allows users to write and edit code, documents, or any other type of text-based information. Unlike word processors, editor programs focus on plain text and do not include formatting features like bolding or italics (though some have extensions for preview). Think of it as a digital notebook for writing and organizing your thoughts or lines of code. It's a basic but crucial tool for any computer user or programmer.
