We introduce the concept of partial application as applied to functions of two arguments and then step by step, with explanatory examples and practical examples along the way, develop implementations for both partial application and currying. The student will gain insight into the underlying principles of currying and partial application and see cool ways to “apply” them in real situations.

In this lesson you will learn how to use partial application to eliminate boilerplate and customize data processing for concise and readable code. Partial application makes it easy to apply functional programming techniques like map, filter, and reduce to transform data while leaving the originals intact.

Write Concise Data Transformations in JavaScript with Partial Application

Produce Multiple Partial Functions with Factory Functions in JavaScript - Generalizing by parameterizing a partial function’s first argument to create a factory function that can produce multiple partial functions differing only in the fixed argument.


Produce Multiple Partial Functions with Factory Functions in JavaScript

We generalize the "unrolled" versions of a couple of binary functions to derive a general "partial" function for binary functions.
