JavaScript array deobfuscation

I'm trying to decode some JS and I've got a good portion of it done, however, I'm stumped here. The code does something like this:

var arr = ["value", "value1", "value2"];
console.log(arr[0]);

Except the file is around 12k lines and there are over 1.4k things in the array. Is there a way I can replace arr[0] with the actual value of arr[0] (in the example, it would be "value"), then save the file? I tried using RegExp but got nowhere.

Any help will be appreciated.
