Everything you need to know about URL encoding
URL encoding converts characters into a format that can be transmitted over the internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.
URLs can only contain certain characters. Special characters like spaces, &, ?, # need to be encoded to be properly transmitted and interpreted by web servers and browsers.
encodeURI preserves characters like / ? & = # that are part of URL structure. encodeURIComponent encodes all special characters, useful for encoding parameter values.
Yes, URL encoding is fully reversible. Decoding returns the original string without any data loss.
