How to have one binary operation performed over a binary array?

Suppose a binary array var arr = [true, true, false];.

Is there any way to get the AND or OR of the whole array using one method?

You could use Boolean as callback for 

var array = [true, true, false];

console.log(array.some(Boolean));  // or
console.log(array.every(Boolean)); // and

You can use every() for an AND:

arr.every(x => x);

And some() for OR:

arr.some(x => x);

Yes: for AND you use arr.every(bool => bool), for OR you use arr.some(bool => bool).
