Discussion on: Currying in JavaScript

View post

This is not partial application in its imperative meaning:

function sum(a) {
    return (b, c) => {
        return a * b * c
    }
}

sum(1);

It is a curried function that returns a multi-argument one.

Partial application is a dynamic concept of imperative programming. Here is a possible approach:

const partial = (f, ...args) => (...args_) =>
  f(...args, ...args_);

const sum = (a, b, c) =>
  a * b * c;

partial(sum, 1) (2, 3); // 6

How partial application have any imperative meaning? Partial application is just possibility of applying to function less arguments than function defines. If function is curried then partial application is just using this function property.
