Braces or Brackets?

Someone forgot whether to use braces or brackets and you have to clean up their code!

Start file

var some_function = function {arg1, arg2} [
        var some_array = (1, 2, 3, 4, 'foo');
        for {var i in some_array} (
                console.log(some_array, [{1 + (8 / 2)}, 'hello (world)');
        )
];

End file

var some_function = function (arg1, arg2) {
        var some_array = [1, 2, 3, 4, 'foo'];
        for (var i in some_array) {
                console.log(some_array, [(1 + (8 / 2)), 'hello (world)');
        }
};
