Best way to check if there is internet?

[Abdur-Rahmaan Janhangeer]

A front end eng sent me this for how to check for the internet in JS

https://html.spec.whatwg.org/multipage/system-state.html#dom-navigator-online

But it also says:

"This attribute is inherently unreliable. A computer can be connected to a
network without having Internet access."

As discussed here but, it would have been nevertheless great to have this
tiny function instead of
nothing
