are you using tabs in development? :)

that task is a perfect candidate for reduce instead of forEach

What do you mean saying "tabs"?

And no, I can't do this task with reduce.

res.push(value);
}else{
subFlatten(value);
}
});
}
subFlatten(arr);
return res;
};

console.log(flatten([[1,2],[3,[4]],5, 10]));
console.log(flatten([25, 10, [10, [15]]]));
console.log(flatten([1, [2, [ {a: "b", c: 'd' }, { c: [1, 2, 5] } ] ] ]));
