FAQ
Component vs Full URL?
encodeURIComponent escapes everything that's reserved in URLs (including / : ? & =) — use it for individual query parameter values. encodeURI is more permissive and intended for whole URL strings — / : etc. are left alone.
Is my input sent anywhere?
No. Encoding/decoding uses the browser's native APIs.
