_.curry

_.curry(func, [arity=func.length])

Creates a function that accepts arguments of func and either invokes func returning its result, if at least arity number of arguments have been provided, or returns a function that accepts the remaining func arguments, and so on. The arity of func may be specified if func.length is not sufficient.

The _.curry.placeholder value, which defaults to _ in monolithic builds, may be used as a placeholder for provided arguments.

Note: This method doesn't set the "length" property of curried functions.

Since

2.0.0

Arguments

1. func (Function): The function to curry.
2. [arity=func.length] (number): The arity of func.

Returns

(Function): Returns the new curried function.

Example

var abc = function(a, b, c) {
  return [a, b, c];
};
 

var curried = _.curry(abc);
 

curried(1)(2)(3);
// => [1, 2, 3]
 

curried(1, 2)(3);
// => [1, 2, 3]
 

curried(1, 2, 3);
// => [1, 2, 3]
 
// Curried with placeholders.

curried(1)(_, 3)(2);
// => [1, 2, 3]
