How to implement regular expression verification port range in js

javascript regular expression to verify the port legitimacy of the IP address

if (!(/^[1-9]\d*$/.test(port) && 1 <= 1 * port && 1 * port <= 65535)){
 return false
}

Tips:

Your port does not comply with the range: 0-65535

Let’s take a look at the JavaScript (Js) regular expression to verify the IP port number. The code is as follows:

var ip="192.168.2.1:8080"
 var pattIp=/^(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\:([0-9]|[1-9]\d{1,3}|[1-5]\d{4}|6[0-5]{2}[0-3][0-5])$/;
 if(pattIp.test(ip)==false)
 {
 return false;
 }
