What is the difference between Component and Full URL?

Component matches encodeURIComponent and is right for one query value. Full URL matches encodeURI and leaves characters such as / ? & = that give a URL its structure.

Why does a space become %20 or +?

Both mean a space. %20 is standard percent encoding; + is used by HTML forms in query strings. Decoding here accepts both.
