FAQ

What's the difference between Component and Full URI mode?
Component mode (encodeURIComponent) escapes every reserved character, including & and = — use it for a single query parameter value. Full URI mode (encodeURI) leaves URL structure characters like :/?& alone — use it when encoding an entire URL.
Why did spaces become %20 instead of +?
%20 is the standard percent-encoding for a space. The + convention for spaces is specific to the application/x-www-form-urlencoded format used in form submissions, not general URI encoding.
