Difference between Observer, Pub/Sub, and Data Binding
...a Binding
Essentially, at the core this just means "the value of property m>X m> on object Y is semantically bound to the value of property A on object B. No assumptions are made as to how Y knows or is fed changes on object B.
Observer, or Observable/Observer
A design pattern by which an object is im...
What is a lambda (function)?

As you can see from the snippet of Python, the function adder takes in an argument m>x m>, and returns an anonymous function, or lambda, that takes another argument y. Tha...
Are loops really faster in reverse?
