When do I need to escape HTML?
Anytime you embed untrusted text inside an HTML document. Failing to escape is the #1 cause of XSS vulnerabilities.
Should I use named or numeric entities?
Named entities (&) are more readable. Numeric (&) work for any Unicode codepoint. Modern HTML accepts both equally.
Will my framework do this for me?
React, Vue, Svelte all auto-escape interpolated values. Manual escaping is mostly for hand-rolled HTML generation or email templates.
