Function curry

Returns a curried equivalent of the provided function.

Curried function can accept one or multiple parameter at the time:

• g(1)(2)(3)
• g(1)(2, 3)
• g(1, 2)(3)
• g(1, 2, 3)

The special placeholder value __ may be used to specify "gaps", allowing partial application of any combination of arguments, regardless of their positions:

• g(1, 2, 3)
• g(_, 2, 3)(1)
• g(_, _, 3)(1)(2)
• g(_, _, 3)(1, 2)
• g(_, 2)(1)(3)
• g(_, 2)(1, 3)
• g(_, 2)(_, 3)(1)

Example

const addNumbers = (a, b, c, d) => a + b + c + d

const addLastNumber = curry(addNumbers)(5, 5, 5)

addLastNumber(5)

const addFirst = curry(addNumbers)(__, 5, 5, 5)
addFirst(5)
