JavaScript Pattern Matching with Asterisks

I want to make something that would check if a string like this:

https://www.example.com/page

Is equal to:

http*//*example.com/*

Or something like this. Is there something built in to JS that does this with asterisks, or should I use a plugin or something?

I was able to create a function that does this, but thank you all for your answers. I will post the code below.

var wildcardCheck = function(i, m) {
   var regExpEscape = function(s) {
       return s.replace(/[|\\{}()[\]^$+*?.]/g, '\\$&');
   };
   var m = new RegExp('^' + m.split(/\*+/).map(regExpEscape).join('.*') + '$');
   return i.match(m) !== null && i.match(m).length >= 1;
};

You can try match() function

let str = 'https://www.example.com/page';

let strMatches  = str.match( /http([\s\S]*?)\/\/([\s\S]*?)example.com([\s\S]*?)/ );

let result = document.querySelector('#result');
if( strMatches!= null && strMatches.length > 0 ){
  result.innerHTML = 'Match';
} else {
    result.innerHTML = 'Mismatch';
}
<div id="result"></div>

There's nothing built in that does what you've literally described. But look at regular expressions, which are the generalized version. The regular expression in your case would probably be /^http.*\/\/.*example\.com.*$/.

Example:

var rex = /^http.*\/\/.*example\.com.*$/;
function test(str) {
  console.log(str, rex.test(str));
}
test("https://www.example.com/page"); // true
test("ttps://www.example.com/page");  // false
