Frequently asked questions
When should I URL-encode text?
URL-encode (percent-encode) any value you place into a query string, path, or form body so characters like spaces, &, =, and non-ASCII bytes don't break or misdirect the request.
What is the difference between encodeURIComponent and encodeURI?
encodeURI leaves reserved URL structural characters (?, #, /, etc.) intact for a full URL, while encodeURIComponent encodes everything so a value can be used as a single query parameter.
