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.
