Lodash _.forEachRight() Method

Lodash _.forEachRight() method iterates over elements of collection from right to left. It is almost the same as the _.forEach() method.

Syntax:

_.forEachRight( collection, iteratee );

Parameters:

• collection: This parameter holds the collection to iterate over.
• iteratee: It is the function that is invoked per iteration.

Return Value:

This method returns the collection.

Example 1: In this example, we are iterating the given array from right to left and printing the value in the console.

Javascript

// Requiring the lodash library
const _ = require("lodash");

// Use of _.forEachRight() method
_.forEachRight(['c', 'cpp', 'java',
    'python'], function (value) {
        console.log(value);
    });

Output:

python
java
cpp
c

Example 2: In this example, we are iterating the given object from right to left and printing the value in the console.

Javascript

// Requiring the lodash library
const _ = require("lodash");

// Use of _.forEachRight() method
_.forEachRight({ 'x': 1, 'y': 2 },
    function (value, key) {
        console.log(key);
    });

Output:

y
x

Note: This will not work in normal JavaScript as it requires the lodash library to be installed.
