Frequently Asked Questions

>What is the difference between URL and component encoding??
encodeURI keeps URL structure characters like /, ?, and & intact, while encodeURIComponent escapes everything so a value can be safely placed inside a query parameter.
>Why does my decoded output contain %20??
%20 is the encoded form of a space. It appears when the original string was encoded with a scheme that does not convert spaces to + (like encodeURIComponent does for query strings).
