The 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: This method accepts two parameters as mentioned above and described below:
- 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:
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:
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.
