How it works
How it works
URL encoding replaces non‑safe characters with %HH hex escapes. Use encodeURIComponent for individual query values, not whole URLs.
- Spaces become
%20(not+which is form‑encoding). - Reserved characters like
&,=,?are encoded in values. - To build full URLs, assemble components with
URL/URLSearchParams.
