URL Encoding Explained

URL encoding (also known as percent-encoding) converts special characters into a format that can be safely transmitted in a URL. Characters like spaces, ampersands, and question marks have special meanings in URLs, so they need to be encoded. encodeURIComponent encodes all special characters (used for query parameters), while encodeURI preserves URL structure characters like ://, /, and ?.
