Why do we need URL encoding?

URLs can only be sent over the internet using the ASCII character-set. URL encoding converts non-ASCII characters and delimiters into percent-encoded hex equivalents.

What is the difference between encodeURI and encodeURIComponent?

encodeURI preserves URL structure characters like ?, =, & and /. encodeURIComponent encodes all special characters to make them safe as single query parameters.
