Lodash _.curryRight() Method

0 0 1 minute read

Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.

The _.curryRight() method is used to return a curried version of the given function where the given arguments are processed from right to left.

Syntax:

_.curryRight( fun )

Parameters: This method takes a single parameter as listed above and discussed below.

fun: This is the function that should be used in the curried version.

Return Value: This method returns the curried function.

Note: This method will not work in normal JavaScript because it requires the Lodash contrib library to be installed. The lodash-contrib library can be installed using npm install lodash-contrib –save

Example 1:

Javascript

// Defining lodash contrib variable 
var _ = require('lodash-contrib');  
  
// Function to curry 
function div(a, b, c) { 
    return a / b / c; 
} 
  
// Using the _.curryRight() method 
var curried = _.curryRight(div); 
  
console.log("Curried division is :", 
    curried(3)(3)(99));

Output:

Curried division is : 11

Example 2:

Javascript

// Defining lodash contrib variable 
var _ = require('lodash-contrib');  
  
// Function to curry 
function div(a, b, c, d) { 
    return a - b - c - d; 
} 
  
// Using the _.curryRight() method 
var curried = _.curryRight(div); 
  
console.log("Curried Subtraction is :", 
    curried(2)(1)(6)(44));

Output:

Curried Subtraction is : 35

Example 3:

Javascript

// Defining lodash contrib variable 
var _ = require('lodash-contrib');  
  
// Function to curry 
function div(a, b, c) { 
    return ("a=" + a + " and b=" + b + 
            " and c=" + c); 
} 
  
// Using the _.curryRight() method 
var curried = _.curryRight(div); 
  
console.log(curried("a")("b")("c"));
