Frequently Asked Questions
What is URL encoding?
URL encoding converts reserved or unsafe characters (such as spaces, question marks, and ampersands) into percent-encoded representation (e.g. %20 for space, %26 for &) so they can be safely transmitted over HTTP.
What is the difference between encodeURI and encodeURIComponent?
encodeURI preserves protocol and domain syntax (like :// and ?), whereas encodeURIComponent encodes all characters including delimiters, making it suitable for query string parameter values.
