URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits representing the character's ASCII code.
URL encoding (percent-encoding) converts special characters into a format that can be transmitted over the internet. Characters like spaces, &, ?, = are replaced with %XX where XX is the hexadecimal ASCII value.
Use URL encoding when passing data in URLs, query strings, form submissions, or API requests. Special characters must be encoded to be properly transmitted.
encodeURI encodes a complete URI, preserving characters like :, /, ?, &. encodeURIComponent encodes everything except letters, digits, and - _ . ! ~ * ' ( ), making it ideal for encoding query parameter values.
