Location: port property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The port property of the Location interface is a string containing the port number of the URL, or the empty string if the port is the default for the protocol.
Note:
If the Location object refers to a URL that 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 URL (e.g., https://localhost:443), then the port property will be the empty string: ''.
Value
A string.
