Jun 21, 2021 · Here's a practical example from React, the JavaScript user interface library. Currying here illustrates the closure property.

The handler typically modifies the application's state and triggers the interface to re-render.
Sep 22, 2016 · I would say that, most probably, all the animation library in JS are using currying. Rather than having to pass for each call a set of impacted elements and a function, describing how the element should behave, to a higher order function that will ensure all the timing stuff, its generally easier for the customer to release, as public API some function like "slideUp", "fadeIn" that takes only elements as arguments, and that are just some curried function returning the high order function ...

Oct 20, 2008 · Currying means breaking a function with many arguments into a series of functions that each take one argument and ultimately produce the same result as the original function. Currying is probably the most challenging topic for developers new to functional programming, particularly because it is often confused with partial application.
The functions in JavaScript are variadic by default, so hacking the language in a such way is harmful, because it may confuse newbies that getting multi-arity fns like this is the way, while it's definitely not.

Also, if you look at the code below, we are running curriedMultiply5() several times, is it true that the benefit of currying is that it helps us run code only once and reuse its output several times, that is, currying helps us achieve efficiency.
