return (x === 15 || y === 15 || x + y === 15 || Math.abs(x - y) === 15);
}
console.log(test_number(15, 9));
console.log(test_number(25, 15));
console.log(test_number(7, 8));
console.log(test_number(25, 10));
console.log(test_number(5, 9));
console.log(test_number(7, 9));
console.log(test_number(9, 25));

How to insert an item into an array at a specific index (JavaScript)?
What you want is the splice function on the native array object.
arr.splice(index, 0, item); will insert item into arr at the specified index (deleting 0 items first, that is, it's just an insert). In this example we will create an array and add an element to it into index 2:
var arr = []; arr[0] = "Jani"; arr[1] = "Hege"; arr[2] = "Stale"; arr[3] = "Kai Jim"; arr[4] = "Borge"; console.log(arr.join()); arr.splice(2, 0, "Lene"); console.log(arr.join());
