Javascript: Check the URL is working / existed / reachable (returning Status 200 / non-broken) or not -

with javascript, want check url reachable (existed, returning http status 200, not 404, etc).

let's say, how know (by using js) that:

• "https://www.google.com" (website) .. reachable link.
• and, "http://code.jquery.com/jquery-1.11.3.min.js" (js file) .. reachable link.
• and, "https://www.microsoft.com/library/errorpages/images/microsoft_logo.png" (image) reachable.

(they not: broken, non-existed, 404, etc).

---

again how know, such:

• "http://www.asderafsdfefrasdfsdfasf.com"
• or, "https://www.google.com/xxxxxxxxxxx.js" ..

are broken, not-reachable, non-existed, 404, etc?
