Syntax

_.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.

Arguments

• func (Function) − The function to curry.

• [arity=func.length] (number) − The arity of func.

Output

var getArray = function(a, b, c) {
   return [a, b, c];
};
 
var curried = _.curry(getArray);
console.log(curried(1)(2)(3));
console.log(curried(1, 2)(3));
console.log(curried(1, 2, 3));
