Tailwind CSS is a utility-first approach that provides predefined utility classes. Sometimes developers want to use CSS variables instead of predefined classes. This article will guide you in effectively using CSS variables in Tailwind CSS. What is CSS Variables? CSS variables are also known as custom properties, which are used to store values in CSS that you can reuse throughout your styles. CSS variables are defined using the --variable-name syntax. Syntax :element { --variable-name: value; } Setting Up CSS Variables To use CSS variables in Tailwind CSS, first ... Read More
Virtual DOM and Real DOM are important terms in web development. They both influence the rendering and updating of user interfaces. Virtual DOM is a transparent overlay that maximizes updates, whereas Real DOM is the underlying structure that the browser manipulates. To maintain optimal performance, web development frequently calls for effective ways to handle user interface (UI) modifications. Given their frequent changes and performance issues, traditional Document Object Models (DOMs) have been replaced by Virtual DOMs in contemporary frameworks. It is very important to understand the differences between Virtual DOM and Real DOM and how current frameworks achieve greater ... Read More
We will be given an array and we have to answer some queries related to the given range that is from a given starting index to the ending point or index we have to return the product of the elements in that range. We will see some approaches in this article to implement the above problem in JavaScript with the explanation. Introduction to Problem We are given an array and some queries, in each query we will be given some ranges by indicating the first and the last index of the range and we have to answer the product of ...

Gnome Sort, also known as Stupid Sort, is a simple sorting algorithm that works by iterating through a list, comparing adjacent elements, and swapping them if they are in the wrong order. If a swap occurs, the algorithm moves one step backward to recheck the order, otherwise, it moves forward. This process continues until the array is sorted. In this article, we will explain the working of Gnome Sort using Java. Gnome Sort Approach Start from the first element. Compare the current element with the previous one: ... Read More
In JavaScript, when dealing with arrays of objects, it’s common to need to extract specific values based on object properties and count how many unique occurrences exist for a particular property. Whether you're processing a list of users, products, or any other data structure, counting unique elements by a property is a useful operation.In this article, we'll discuss how to count the number of unique elements in an array of objects based on a specific property using a few different techniques. Problem Statement You have an array of objects representing users, each with properties like name, age, gender, etc. You ... Read More
To find k pairs with smallest sums in two arrays in Javascript, we will be using sorted arrays in ascending order. We are going to discuss two different approaches with stepwise explanation and examples. In this article we are having two arrays and a value of k, our task is to find k pairs with smallest sums in two arrays. Users must be familiar with JavaScript arrays, loops and conditional statement. Example Input: arr1 = [1, 7, 11], arr2 = [2, 4, 6] k = 3 Output: [[1, 2], [1, 4], [1, 6]] Input: arr1 = [1, 4, ...

JavaScript is a powerful and versatile programming language that is widely used for both front-end and back-end development. One of the features that makes JavaScript so powerful is its extensive standard library, which includes many built-in methods for working with strings, arrays, and other data types. One such method is the at() method, which was introduced in ECMAScript 2022 and is used to retrieve the character at a given index in a string. In this tutorial, we'll take a look at how to use the at() method, as well as explore some of its advantages over the older charAt() method. ... Read More
Simple Interest is the interest calculated only on the initial principal amount taken. This is not like compound interest where interest is compounded, i.e., previous interest is included in the current time period. This interest is simple and grows linearly over time. In this article, we will discuss how to calculate simple interest using C#. The formula to calculate Simple Interest is: Simple Interest (SI) = P × R × T / 100 Where: p is the principal amount r is the interest rate t is ... Read More
What is a Circle? A circle is a round two-dimensional shape in which all the points on the surface of the circle are equal from a point known as the center. The distance between the center and any point on the boundary of a circle is known as the radius. Area of a Circle The area of a circle is the total area present inside the boundary of a circle. In this article, we are going to discuss different approaches on how we can calculate the area of a circle using C#. The formula for the Area of the ... Read More
Problem Description We are given an array, we have to check whether the array is sorted or not. The array can be sorted in both ascending or descending order. In this article, we are going to discuss different approaches to check if an array is sorted or not using C#. Example Input: array = {1, 2, 3, 4, 5} Output: True Explanation: The array is sorted in ascending order. Input: array = {29, 28, 27, 26, ... Read More
