Each method has its own advantages and disadvantages, and it is important to consider which method works best for the given task. The intersection of two arrays is helpful if you want to create a new array that contains only the elements found in both arrays. Let’s have an example − arr1 = [ 2, 5, 7, 9, 11, 13, 15, 17 ] arr2 = [ 1, 3, 5, 7, 11, 13, 16, 17 ... Read More

Arrays are one of the most commonly used data types in JavaScript. They are used to store collections of data and allow for efficient access and manipulation of data. Arrays can contain any type of data, including primitive values, objects, and even other arrays.

In JavaScript, an object contains the key-value pair. Sometimes, we may require to sort the object keys. We can’t use the sort() method directly with the object as like array, as we need to sort the key-value pair of the object together rather than sorting only keys. Below, we will learn various methods to sort the object keys in ascending and descending order. Use the sort() method to order keys in JavaScript objects We can use the Object.keys() method to get all keys of the object in the array. After that, we can use the array.sort() method to sort ...
