In this article, we will learn about the Multiplication assignment operator (*=) in JavaScript. In general, we use a = a * b this expression to update the value of a variable with the value returned after multiplying its original value with some other value, which is easy to understand, but it time taking to write again and again if we are using updating values of more variables like this. So, to overcome this problem, JavaScript introduces us to the multiplication assignment operator (*=) as it is the short form for using the above expression. The multiplication Assignment operator (*=) ... Read More
The less than operator is one of the operators that come under the category of binary operators, which means it requires two operands to operate on. It will return true if the operand on the left side of the operator is less than the operand on the right side. Otherwise, it will return false. The less than operator come under the category of comparison operators that compare two values with each other. In this tutorial, we are going to discuss what is less than an operator in JavaScript and how it works in different situations, with help of code examples. ... Read More
React is a popular JavaScript library used to build user interface components. One of the features of React is that it allows you to use arrow functions to define React components. You may now create components using both the standard JavaScript function and the arrow function syntax, thanks to the release of ES6 arrow function syntax. Lets discuss what arrow functions are and why you should use them in your ReactJS code − About Arrow Functions The arrow function is a new feature of ES6, introduced in ReactJS 16. It allows the developer to create a function that has lexical ... Read More
One of the many amazing things about React is that it’s more visually appealing than traditional web development frameworks like AngularJS. This might be because React favors a "simple" and "elastic" design over complex directives and components. Other factors contributing to React's visual appeal are the use of stateless components and declarative rendering. This means that instead of specifying how each component should look, you simply specify what data it needs and React will take care of the rest. In the end, it really depends on your personal taste − some people might prefer AngularJS' more polished look, while others ... Read More
DOM stands for ‘Documents Object Model’. It’s the World Wide Web Consortium's fundamental logical homepage model. Every time the UI state of an application changes, the DOM is updated to reflect the change. Whenever the application user interface is updated, the DOM is rendered which ultimately impacts the application performance, resulting in slower loading. The complexity of the DOM and the numerous UI components further depletes the performance because each change necessitates a new rendering of the page. However, the virtual DOM concept in React has changed everything. Let’s see below − What is DOM? To put it another way, ... Read More
Client−side rendering is a technique used in web development to improve the performance of web pages. It moves the browser’s rendering process from the server to the client. This way, there is no need for a round−trip request to render a page. Let's start by discussing what occurs when your program requires client−side rendering. React applications are developed by calling one or several JavaScript modules from a simple HTML document while utilizing only the CLI or React command create−react−app. The HTML of each page is created and loaded into the website by JavaScript, which automatically adds it to the document's ...

Single Page Applications or SPAs are beginning to rule the IT marketplace now. (And for good reasons!) They are incredibly fast and render an amazing user experience. But what makes them faster? Well, the reason is that the SPAs enable the users to navigate through several pages without having to refresh the page. As the single page applications dynamically rewrite the web page content from the server, they do not load the entire web page after every render. This way, the web pages potentially improvise the performance by creating a more dynamic user experience. Let’s learn about the ... Read More
The front−end development ecosystem is constantly changing. It is getting harder for business owners to choose the finest library or framework from the many available since new tools are released daily. Speaking of frontend, React.js have been setting records in the web development industry for some time and doing splendidly despite having huge competition. Why is it so? How is it that react has been able to rule the IT industry while other libraries are still struggling? We’ll get all these answers in this blog. So, let’s dive in − What is React.js? React is an open−source, front−end JavaScript library, ... Read More
React Hooks open up a completely new approach to constructing functional components, enabling us to include capabilities like stateful logic that are only available for class components. React mostly makes use of its built−in hooks, useState and useEffect Hooks, to do this. These hooks j In this article, we will go over what hooks are and how they can be used to create applications with React. We will also see how they simplify everyday development workflows. All About React Hooks As quoted by team React− “React Hooks are a new feature of React.js that makes it possible to use ... Read More
In this tutorial, we are going to learn to set a default parameter value for a JavaScript function. JavaScript is an object-oriented programming language that provides us the facility to perform both functional and class-oriented programming which gives us the facility to manage code easily and can re-use the code as well. In functional programming, the programmer creates a function that may take some parameters and may return some value after performing a number of steps it was supposed to do. The value of parameters for the function can be a string, number, object, etc. and we can also set ... Read More
