What is URL Encoding?
URL encoding (percent-encoding) converts characters that are not allowed in URLs into a safe format using a % followed by two hexadecimal digits. For example, a space becomes %20 and& becomes %26. This ensures URLs transmit correctly across all browsers and servers.
encodeURI vs encodeURIComponent
encodeURI encodes a complete URL but leaves structural characters (://,/, ?, #) intact. encodeURIComponent encodes every special character and is the right choice for individual query parameter values or path segments.
