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.
// 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.
// 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.
