Wikipedia has the following to say about currying:
In mathematics and computer science, currying is the technique of translating the evaluation of a function that takes multiple arguments (or a tuple of arguments) into evaluating a sequence of functions, each with a single argument. Currying is related to, but not the same as, partial application.
https://en.wikipedia.org/wiki/Currying
Instead of putting multiple arguments in one function, I call a function multiple times, passing in one argument each time. I have done three different versions using normal formatting, and fat arrows.

// Basic Curry example function curryName(name) { return function(descrip) { return function(location) { return name + " is a " + descrip + " from " + location; }; }; }; // With arrow functions function curryName(name) { return descrip => { return location => { return name + " is a " + descrip + " from " + location; } } }; // Function expression const curryName = name => descrip => location => name + " is a " + descrip + " from " + location; const output = curryName("Brian")("Web developer")("San Diego"); console.log(output); // Brian is a Web developer from San Diego |
