Java Reference
In-Depth Information
• A mixin method can be used to add properties and methods from other objects
without creating an inheritance chain.
• Methods can be changed together and called in sequence if they return a reference
to
this.
• Polymorphism is when the same method is used by two unique objects in different
ways.
• The value of
this
is not retained inside nested functions, which can cause errors.
This can be worked around by using
that = this
or using the
bind(this)
method.
• Methods can be borrowed from objects.
In the next chapter, we'll be looking at how to send and receive data using JavaScript.

There's more about shallow and deep copies
later in the chapter.

The Ruby programming community, on the other hand, generally embrace monkey-
patching, so it is quite common in Ruby code examples.
