How it works

URL encoding (percent-encoding) replaces unsafe characters with a % followed by two hex digits.

encodeURIComponent - Encodes everything except A-Z a-z 0-9 - _ . ! ~ * ' ( ). Use for query parameters.
encodeURI - Preserves URL structure characters like : / ? # & =. Use for full URLs.

Decode reverses the encoding, converting percent-encoded characters back to their original form.
