In JavaScript, redirecting a user from one URL to another is a straightforward task. There are multiple ways to achieve this, but we’ll focus on two of the most common and effective methods: window.location.href and window.location.replace(). Both are widely used for different purposes, and understanding when to use each one can help improve user navigation on your site. Approaches to Redirect a URL in JavaScript Following are the different approaches to redirect a URL: Using window.location.href Using window.location.replace() Redirect a URL Using window.location.href Property The window.location.href property is one of ...

To find closest number in array using Javascript, we will be understanding and discussing three different approaches. We will also compare time and space complkexities of all the appproaches used. In this article we are having an array and a target value, our task is to find closest number to target value in array using Javascript. User must know about JavaScript arrays, searching alogorithms such as linear and binary search, sorting, loops, and conditional statement. Approaches to Find Closest Number in Array Here is a list of approaches to find closest number in array in JavaScript which we will ... Read More
Here we will see five different ways to get the string lengths in C++. In C++ we can use the traditional character array string, and C++ also has String class. In different area there are different methods of calculating the string lengths. The C++ String class has length() and size() function. These can be used to get the length of a string type object. To get the length of the traditional C like strings, we can use the strlen() function. That is present under the cstring header file. Another two approaches are straight forward. One by using the while loop, ... Read More
Here in this program we will see how to iterate through each characters of a string in C++. To loop on each character, we can use loops starting from 0 to (string length – 1). For accessing the character we can either use subscript operator "[ ]" or at() function of string object. Input: A string "Hello World" Output: "Hello World" Algorithm Step 1: Get the string Step 2: Use R before string to make it raw string Step 3: End Example Code #include using namespace std; int main() { string my_str = "Hello World"; for(int i = 0; i
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, ...
