In this article, we are going to learn about the methods of sorting a numerical array in JavaScript. Sorting of an array means to arrange the elements of an array in a particular order i.e. they can be in ascending or the increasing order and they can be arranged in descending or the decreasing order. There are two ways in which we can sort a numeric array in a particular order in JavaScript − By traversing array with the help of loops By using the sort() method available in JavaScript Let us discuss both of the above methods ...

Generally, we sort arrays, objects and some other data types using some method of JavaScript. But, in this article, we are going to sort the child elements of an element whose values are in unsorted order using the data attribute of those child elements. In this article, we are going to learn about the two different ways or methods of sorting the child elements according to the value of their data attribute given to them. The methods we use to sort are listed below − By selecting the value of data attribute using the getAttribute() method. By selecting the ... Read More

A array with multiple columns is an array that contains multiple elements at single index or position OR we can say that it is an array of arrays that contains multiple arrays at each index of it and we have to sort that array according to the elements of those contained arrays. In this article, we are going to learn about the method of sorting an array of arrays with the help of sort() method. We will use the comparator function to compare the elements of inner arrays with each other and sort them accordingly. Let us see how we ... Read More

An array of objects is an array that contains all the elements in the form of JavaScript objects. Here, we are said to use an array of objects with two fields that means, have to use objects with two elements as elements of the array. In this article, we are going to learn about the method of sorting the array of objects by two fields in JavaScript. We can simply use the sort() method of JavaScript to sort the elements of an array and give it a cmp or the comparator function to define the order in which we want ... Read More

A set is also a data structure that is almost similar to the map data structure. The only difference between them is that map stores the elements in the form of key-value pair, while set does not it only stores a single value in the same order as it was inserted. It can also store primitive data types as well as objects as map does. A set contains all the elements in the same order as they are inserted. But, we can sort a set in any order whether in increasing or decreasing order of elements using the sort() method ... Read More

In JavaScript, Map is a type of data structure that stores the values in the form of key value pairs. It can store all types of data types, whether they are primitive or JavaScript objects. It stores the elements in the same order in which they are inserted, hence, when we iterate through its elements, it prints the elements in the same order as we have stored them. As we have discussed that the order of elements stored in a Map is same as we insert elements in that Map. But, we can also sort the elements of the map ... Read More

The performance.now() method is used to calculate the performance of the code written by any programmer or the coder. The performance.now() method will return a numerical value that will be the time taken by the written code to execute. The value returned by this method may vary every time we execute the code even for the same code. In today’s time, everyone wants to write the fast loading and the efficient code for a problem that can work on every parameter and fastest of all other solutions. So, to measure the efficiency and to make sure that the written code ... Read More

Overview A class in any element defines the type of the data contained in an element. A same class name can be taken by another tag or element also. There is no such property for the class attribute that the class name should be unique. To find whether all the elements contain the same classes or not, can be achieved with the help of HTML, CSS and JavaScript. The HTML provides the layout of the page and the layout for the elements for the same classes and the JavaScript will provide the functionality to check whether all the elements contain ...
