Preguntas frecuentes
What characters are encoded in URL encoding?
Reserved characters like spaces (%20), ampersands (%26), slashes (%2F), and non-ASCII characters are percent-encoded.
What is the difference between encodeURI and encodeURIComponent?
encodeURIComponent encodes reserved delimiters like & and = so they can be safely passed inside query parameter values.
