I was wondering how I could see if a website returns a 404 Error. I've heard of https://httpstatus.io/, but I don't think I can use it in JavaScript and for what I need (but if I can, please tell me . . .)
EXAMPLE: my site is tilier.com/hello, and I want to see if banana.co/banana returns a 404 error. How can I do this?
Also, my site is not actually tilier.com.
