Frequently Asked Questions
Why do URLs need encoding?+
URLs can only contain a limited set of ASCII characters. Special characters like spaces, &, =, and # have reserved meanings in URLs. Encoding converts these to safe %XX representations so they're treated as literal data rather than URL structure.
What is the difference between encodeURI and encodeURIComponent?+
encodeURI encodes a full URL but preserves structural characters like ://?#. encodeURIComponent encodes everything except letters, digits, and a few safe characters — use it for encoding individual query parameter values.
