Update 13 July 2021
The new at() method allows you to use negative indices to mean “from the end”.
You can access the last item of locArray like this:
if (locArray.at(-1) === ‘index.html’) {
// do something
} else {
// something else
}
At time of update, the at() method is supported in Chrome 92+, FireFox 90+, Node 16 and Deno 1.12+

if (loc_array[loc_array.length – 1] === ‘index.html’) {
// do something
} else {
// something else
}
In the event that your server serves the same file for “index.html” and “inDEX.htML” you can also use: .toLowerCase().
Though, you might want to consider doing this server-side if possible: it will be cleaner and work for people without JS.
Not sure if there’s a drawback, but this seems quite concise:
arr.slice(-1)[0]
or
arr.slice(-1).pop()
Both will return undefined if the array is empty.
