Using Fetch response in a if statement

Question

I have a fetch function that takes a URL and gives out the response.

public getHTTPResponse(URL : string) {
    fetch(URL).then(function(response) {
        return response;
    })
}

I try to use the response in a IF-statement.

For example if the response is 200 it should be true. So far I have:

if (this.getHTTPResponse(item.ListUrl) === )

Where item.ListUrl is a link. I can't get my head around on what I should have on the right side of the operator to test if the response is 200 (or any other for that matter). Any help?

You can't do anything on the right hand side; getHTTPResponse doesn't currently return anything, and if it did comparing promise equality rarely makes sense. — jonrsharpe, Nov 18 '18 at 09:26

Can you post your success and failure response here so we can see what type of response it's returning — Prashant Pimpale, Nov 18 '18 at 09:58

The response object has a property status which value is an integer. Try like that:

  fetch(URL)
   .then(function(response) {
      if(response.status === 200) {
         // do something
       };
     })
