What Is The Underscore Function For?

I've been using underscore as a collection of statics. What is the underscore function for: var _ = function(obj) { if (obj instanceof _) return obj; if (!(this instanceof

Solution 1:

You also can use Underscore as a wrapper function, to get a more OOP-like style:

_(val).method(…);
// instead of the equal
_.method(val, …);

These wrapper objects also allow chaining:

_.chain(val).method1(…).method2(…);
// or
_(val).chain().method1(…).method2(…);

Solution 2:

You wrap objects with it:

_([1, 2, 3, 4]);

And then use Underscore functions on the wrapped object:

_([1, 2, 3, 4]).shuffle()
