Introducing Javascript

You will find JavaScript code everywhere…on the web browser (Angular, React), on the server-side (Node), on mobile, desktop, games, in the Internet of Things, robotics, virtual reality, etc.

Node.js is popular among developers. This backend JavaScript framework is ideal for building highly-scalable, data-intensive, and real-time apps. Its package ecosystem, npm, is the largest ecosystem of open source libraries on a global scale. If you’re building real-time applications with chat features like WhatsApp or collaboration features like Google Docs, this backend JavaScript framework is the obvious choice.

Developers also love Vue.js, a progressive JavaScript front-end framework. It’s a popular open-source tool for creating modern applications and its npm download count is now at nearly 350,000 downloads per week. Lightweight, flexible, and highly performant, Vue has all the properties for a smooth and easy development.

How Good Is JavaScript For Your Web Application Development?

The most notable benefit JavaScript code can bring to your web application development is that it allows you to build an interactive website. Almost everything you interact with on a website is enabled by JavaScript.

You can use JavaScript to develop highly interactive web applications, fast and reliable interfaces and even deliver app-like, offline experience with Progressive Web Apps (PWAs). Using JavaScript has its benefits, including a large base of developers, rich data that can be quickly passed through the DOM layer, and with ReactJS you have support for both raw and JSX JavaScript.

Another powerful side of JavaScript is that there are a lot of frameworks built on top of it, that not only make frontend development easier, but they also simplify the mobile development. With React Native JavaScript became popular in the mobile development industry. The library saves time, shortens the development process, and decreases invested human and financial resources. On the plus side, being a JavaScript framework, it makes the transition from web to mobile development smoother.

JavaScript code can pair with Karma for solid testing capabilities. Karma is a test runner for JavaScript that runs on Node.js and works well with any JavaScript framework. It lets developers get instant feedback on how the code they’ve written will perform.
