Thanks to JavaScript, the web is now a much more interactive and dynamic place.

JavaScript is a programming language, that has given a new experience to the webpages. It all started with a lightweight scripting language for webpages at the beginning, now it is one of the most used and preferred languages in the field of web-development. Due to its features, websites are now dynamic, interactive and multifunctional.

JavaScript changed the web

At the beginning, JavaScript had a significant impact on webpage interactiveness. The user experience was not good before the invention of JavaScript, the navigation between the pages were done by clicking hyperlinks, pages required reloads to update content or respond to user input because webpages were needed to do server-side processing for any kind of operation.

Example of early webpage

However, in the beginning developers used JavaScript mainly for creating dropdown menus, slide shows, and pop-ups. This made the user experience excellent, and made it easier to navigate complex websites.

It has also introduced real time responsiveness, which led to the creation of interactive forms. For example, when a user types into a search bar, it can perform auto-complete options or filter search results in real time.

Introduction to Dynamic webpages

It introduced the ability to update and refresh web pages dynamically, without the need for page to reloads. This was made possible through a technique known as AJAX (Asynchronous JavaScript and XML), which allows web pages to communicate with servers in the background, fetch data, and update content dynamically. For example, when scrolling through a social media feed, JavaScript can be used to dynamically load more content as the user reaches the bottom of the page, without requiring a page reload.

It is also used in a wide range of other contexts, from desktop and mobile app development to game development. JavaScript frameworks and libraries such as React JS, Vue JS, and Angular JS have made it easier than ever to build complex applications and interfaces.

JavaScript as programming language

JavaScript can be used in variety of purposes, making it one of the most flexible and adaptable programming languages in the existence, from webpages to web-based software applications, we can use it everywhere.

Server-side usage of JavaScript

JavaScript can also be used in server-side development (for example NodeJS), allowing developers to create powerful and stable web applications that can handle high levels of traffic and user demand. It can be used to create back-end server logic, database connectivity, and other essential components of modern web applications.

Future of JavaScript

JavaScript is constantly evolving along with the new technologies, the rise of new frameworks and libraries are responsible for JavaScript’s bright future. Some of the popular frameworks are React JS, Vue JS, and Angular JS. These frameworks provide components and libraries, which make it easier and less time consuming for creating complex webpages and webapps.  

It has introduced serverless computing, which allows developers to create web applications without having to worry about managing server. Instead, the cloud provider takes care of the server-side logic, allowing developers to focus on writing code to create user experience better.     

It is also focusing on the performance and speed for smart phones in the low bandwidth area.

In conclusion, JavaScript is a great programming language which changes the web in many ways, it is going to continue like this.
