Have you ever tried to build a custom search engine? If yes, you are aware of how much effort it takes. The first thing is that we need to create a search algorithm that should show the best matching results when any user searches. It can take a lot of time. Rather than wasting time on creating our search engine, what if we use the Google custom search engine? Yes, you heard right! Google allows us to integrate the search engine on our website, and Google handles everything when any user searches for something on our website. Integrating the Google ... Read More

Sometimes, developers may require to store the function in the queue and execute it in the order it is stored in the queue. In JavaScript, we can create a queue using the array. We can use the push() method of the array to enqueue the function in the queue and the shift() method to deque the function from the queue. Below, we will see examples of storing JavaScript functions in the queue and executing them in the queue order. Syntax Users can follow the syntax below to store JavaScript functions in a queue and execute in that order. while (queue.length ... Read More

Storing data in the DOM means storing data in plain text format. For example, we store data in the state variable while using React or any other reactive framework. When the user updates the data in the input field, it stores updated data in the state variable. So, we store data in the state variable before we submit the form. At the time of submitting the form, we use the values of the state variables. In vanilla JavaScript, we can do the same, like storing data in plain text format, and whenever we require to submit the form, we can ... Read More

In some text editors, when you select the text, it shows the menu to edit texts and provides functionalities like justifying text, aligning text, increasing the text size, changing colour, etc. Microsoft word is the best example of it. In Microsoft word, when you select any text, it shows the custom horizontal menu to perform some actions on the text. This tutorial will use JavaScript to create a custom menu on the text selection. Syntax Users can follow the syntax below to show some custom menu on text selection. let coOrdinates = document.querySelector(".content").getBoundingClientRect(); let posX = clientX - Math.round(coOrdinates.left) + ...

The pagination allows users to show content on different pages. For example, we have thousands of data and want to show that to users on a single webpage. It will look worse if we show thousands of data on a single page, as users must scroll through all data to reach the last data. So, to solve the issue, pagination comes into the picture. We can show a particular number of data on a single page and create a total number of pages according to the total data available. Gmail is the best example of pagination, it shows 50 emails ...

To get maximum and minimum in a Square Matrix in JavaScript, we will be discussing two different approaches, their complexities, and example codes. First approach make use of nested loop while second approach uses Math function. In this article we are having a 2D square matrix, our task is to write a JavaScript program for maximum and minimum in a square matrix. Example Input: Matrix: [ [1, 3, 7], [5, 2, 9], [2, 5, 1] ] Output: Maximum = 9, Minimum = 1 ... Read More

In this article, we will implement the JavaScript program for the Maximum sum of i*arr[i] among all the rotations of the given array. Here i*arr[i] expression indicates that we have to maximize the sum of all the elements of the array by taking the product of them with the current position. We can rotate the given array elements in the left of the right position to get the maximum answer. For this problem, we will see a complete code and a deep explanation. Introduction to Problem In this problem, we are given an array and if we multiply all the ... Read More

A subarray is part of an array formed by removing some or no prefixes of the array and removing some or no suffix elements of the given array. We will try to find the subarray that will contain the elements, and by multiplying all of them, we can get the maximum value. We will implement the code with the explanation. In this article, we will implement a JavaScript program for the Maximum product subarray. Introduction to Problem In this problem, we are given an array and we have to pick any subarray from the given array, but the issue is ... Read More

In this article, we are going to implement a JavaScript program for Maximizing elements using another array. We are given two arrays and have to pick some elements from the second array and replace the elements of the first array. We will see the complete code to implement the concepts that will be discussed. Introduction to Problem In this problem, we are given two arrays and we have to make all the elements of the first array maximum as possible or simply we have to make the sum of all elements of the first array maximum. We can pick elements ... Read More

A matrix is a kind of 2-D array, which is in the form of some number of rows, and for each row, there is the same number of columns and by the row and column number, we can get the element at any particular index. For the Markov matrix, each row's sum must equal 1. We are going to implement a code to create a new Markov matrix and find if the currently given matrix is a Markov matrix or not. Introduction to Problem In the given problem, we have to write a code that will produce the Markov ... Read More
