JavaScript

Objects in JavaScript are collections of key/value pairs. The values can consist of properties and methods, and may contain all other JavaScript data types, such as strings,…

Two important ideas in JavaScript with roots in functional thought are currying, which transforms a function of multiple arguments into a series of function calls, and partial application, which fixes the value of some of a function’s arguments without fully evaluating the function. In this article, you will use partial application to fix arguments to a function, curry functions to facilitate partial application, and design functions that facilitate partial application.
