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.
