Returns true if a value is any of the object types: array, regexp, plain object, function or date. This is useful for determining if a value can be extended, e.g. "can the value have keys?"

EventEmitter3 is a high performance EventEmitter. It has been micro-optimized for various of code paths making this, one of, if not the fastest EventEmitter available for Node.js and browsers. The module is API compatible with the EventEmitter that ships by default with Node.js but there are some slight differences:

• Domain support has been removed.

• We do not throw an error when you emit an error event and nobody is listening.

• The newListener and removeListener events have been removed as they are useful only in some uncommon use-cases.

• The setMaxListeners, getMaxListeners, prependListener and prependOnceListener methods are not available.

• Support for custom context for events so there is no need to use fn.bind.

• The removeListener method removes all matching listeners, not only the first.
