How to use sort() method and Lodash _.reverse() function in Javascript
- In this appraoch, we are using Lodash _.reverse() method for reversing the given array.
- We first sort our array then we will reverse it by using _.reverse() method and print the result in the console.
Example: This example implements the above approach.
Javascript
// Requiring the lodash libraryconst _ = require("lodash");// Original arraylet array1 = [1, 7, 3, 4]// Printing original Arrayconsole.log("original Array1: ", array1)array1.sort();// Using _.reverse() methodlet reversedArray = _.reverse(array1);// Printing the reversedArrayconsole.log("reversed Array: ", reversedArray) |
Output:
original Array1: [ 1, 7, 3, 4 ]
reversed Array: [ 7, 4, 3, 1 ]
Sort an array in reverse order JavaScript
Sorting is a basic algorithm that is used in many programming languages. Most languages provide in-built methods to sort an array. In JavaScript we use the sort() method to sort an array in ascending order. To sort an array in the reverse order that is descending order there are no built-in methods to perform this task but we can combine different methods together to sort the array in reverse order.
These are the following methods for solving this problem:
