Q
What is currying?
A
Currying refers to the process of transforming a function with multiple arity into the same function with less arity. The curried effect is achieved by binding some of the arguments to the first function invoke, so that those values are fixed for the next invocation.
Currying can be integrated with callbacks to create higher-order ‘factory’ functions. This pattern is extremely useful in event handling, and can also replace the callback pattern that is utilized in node.js
