 > If an input string passed to the [`URL()`](/en-US/docs/Web/API/URL/URL) constructor doesn't contain an explicit port number (e.g., `https://localhost`) or contains a port number that's the default port number corresponding to the protocol part of the input string (e.g., `https://localhost:443`), then in the [`URL`](/en-US/docs/Web/API/URL) object the constructor returns, the value of the port property will be the empty string: `''`.
