›Why do I need to escape HTML?
To prevent special characters from being interpreted as HTML tags. < becomes < so the browser shows the character instead of opening a tag.

At minimum: < > & " '. For maximum safety, escape every non-ASCII character to numeric entities like 😀.

No — runs entirely in your browser.
