Encode component vs encode full URL
Encode component (encodeURIComponent) escapes everything except letters, digits and -_.!~*'(). Use it for a single query value or path segment, so characters like & and / inside the value can't break the URL.
Encode full URL (encodeURI) keeps characters that give a URL its structure, such as : / ? # & =. Use it for a complete URL that has spaces or non-ASCII characters in it.
Why are spaces sometimes + and sometimes %20?
HTML form submissions (application/x-www-form-urlencoded) encode spaces as +. Everywhere else in a URL a space is %20.
