The following recursive code will cause a stack overflow if the array list is too large. How can you fix this and still retain the recursive pattern?
var list = readHugeList();
var nextListItem = function() {
var item = list.pop();
if (item) {
// process the list item...
nextListItem();
}
};

Write a sum method which will work properly when invoked using either syntax below.
console.log(sum(2,3)); // Outputs 5
console.log(sum(2)(3)); // Outputs 5
