Extended Knowledge

WYSIWYG (What You See Is What You Get) is an editing paradigm where the display during editing matches the final output. Modern browsers provide native rich text editing via the contentEditable API and execCommand methods. Compared to third-party editor libraries like TinyMCE and CKEditor, native API-based editors are lighter and require no additional loading, ideal for quick editing tasks. Note that execCommand has been marked as deprecated by W3C, but all major browsers still fully support it.
