URL Encode & Decode (Percent Encoding)

Two modes matching the two everyday cases: encodeURIComponent (for a single parameter value) and encodeURI (for a full URL). Decode mode accepts either. Spaces, symbols, and non-ASCII characters are converted per RFC 3986.

Runs locally — query strings often contain session identifiers, so keeping them off servers is sensible.

Component mode escapes reserved characters like & and = so a value can be embedded safely in a query string; full-URL mode keeps the URL structure intact.
