Regex URL no numbers

I want to only execute a function if the main part of the URL is NOT followed by any numbers. For example, I want the following URL to match:

http://link.com/groups

but not

http://link.com:8001/ or http://link.com:8000/?alert=true

I've gotten together the regex /link.com[^0-9]+/ but it still matches the first part of the links I don't want matched so when I have the statement:

   var link = document.URL;
   var re = /link.com[^0-9]+/;
   if (re.exec(link)){
      console.log("hello");
   }

"hello" still gets logged out. Is there a way to only execute the function if there are no numbers after the main part of the URL even if part of the URL matches?

Use a negative lookahead (?!...)

/link\.com(?!:\d)/


var link = "http://link.com:8000/?alert=true";
var re = /link\.com(?!:\d)/;
if (re.exec(link)) {
  console.log("hello");
} else {
  console.log("no match");  
}
