Lodash _.curry() Method

Lodash _.curry() method returns a curried version of the given function. it accepts an arity which is a number that shows it will keep accepting arguments until it has received this number of arguments or invocings.

Syntax:

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

Parameters:

• fun: This is the given function.
• [arity=fun.length]: The arity of the function

Return Value:

• It returns a curried version of the function.

Example 1: In this example, we are passing numbers to the gfgFunc which stores the result of the lodash _.curry method and prints the result in the console.

// Defining lodash contrib variable let _ = require('lodash'); // Function function fun(a, b, c, d) {  return a + b + c + d; } // Making curried function let gfgFunc = _.curry(fun); // Only operates for arguments same // as the number in function console.log("Addition is :",  gfgFunc(42)(23)(20)(30)); // Not adds for less arguments console.log(gfgFunc(1)(2)(3)); 

Output:

Addition is : 115

Example 2: In this example, we are passing numbers to the gfgFunc which stores the result of the lodash _.curry method and prints the result in the console.

// Defining lodash contrib variable let _ = require('lodash'); // Function function fun(a, b, c) {  return a * b * c; } // Making curried function let gfgFunc = _.curry(fun); // Only operates for arguments same // as the number in function console.log("Multiplication is :",  gfgFunc(20)(23)(27)); // Not multiplies for less arguments console.log(gfgFunc(1)(2)); 

Output: 

Multiplication is : 12420
