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
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
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

In this tutorial, we are going to learn to set a JavaScript cookie with no expiration date. Web servers deliver cookies, which are tiny files with frequently unique identifiers, to browsers. Each time your browser requests a new page, the server will receive these cookies. It allows a website to keep track of your preferences and online behavior. The expiration option in a JavaScript cookie is optional. The “expires” attribute is optional. If you provide this attribute with a valid date or time, then the cookie will expire on a given date or time, and thereafter, the cookies' value will ... Read More
