As we know Java is one of the best programming languages to learn in the world. And in this post, we are going to share top 7 JavaScript trends to look for in 2019.
In the Principle of least power, Jeff Atwood highlighted that any application that can be written in JavaScript will eventually be written in JavaScript. According to Stack Overflow Report, JavaScript is one of the most prevalent software development languages for many years.
Why is it so widespread? In the ever-evolving world of technology, software development tools and platforms are endeavoring to make the development process more streamlined and business efficient. JavaScript family is the leader in the area with new integrations appearing often. Here is a look at the top JavaScript trends to anticipate in 2019.
Top 7 JavaScript Trends to Look for in 2019
1. JavaScript Front-End Development Frameworks
When talking about JavaScript trends it is natural, to begin with, React JS. It offers great dynamics for creating and handling the change in the document. Its ability to simplify the creation of interactive user interfaces and its comfortable synchronicity with other libraries or JavaScript frameworks like AngularJS is outstanding. Business giants like PayPal, Facebook, Uber, Netflix, and BBC use it. As such it is apparent that its popularity is not likely to change off the top rank in 2019.
Angular is another quite powerful and popular JavaScript framework used by giants such as Weather.com, Forbes, and Google for the development of single web page applications. It offers a two-way data binding and its opinionated structure ensures that all project function similarly. New Angular versions regularly come out. Currently, Angular 7, is already available with updated features.
Open source Vue.js is becoming popular and is particularly designed for web interfaces. It is lightweight and flexible to be used as either part of an existing app or as the focal framework for a site. Its components are well-combined with HTML, CSS, and JS. The main features to expect from Vue in 2019 are; improved performance with Vue.JS 2.x, native Typescript support, proxy support, SVG animations among others.

2. JavaScript Back-End Development Frameworks
JavaScript tools provide several additional capabilities for back-end development as the constituent elements of web development.
According to Stack Overflow Survey, Node.js tops the popular back-end JavaScript technologies for a few years in a row thanks to its productive, fast and scalable features. Node.js leads the way with the JS server-side programming. Node.js provide high performance and speed for:
- Applications having real-time messaging and notifications
- Data-heavy and content-intense apps with a lot of data to be processed
- E-commerce applications dependent on processing speed
Uber, LinkedIn, and eBay utilizes Node.js for excellent user experience. It’s pushing its way as the most reliable, efficient and secure back-end development tool in 2019.
3. JavaScript Cross-Platform Mobile App Development Framework
Mobile app development is a vital part of the current development environment. JavaScript offers a range of trending tools for astounding application development. If you opt to develop a native app, you will need to build two separate ones; Android and IOS applications. However, you can utilize React Native to create a single application able to run on both platforms. Here are some of its noticeable business benefits:
- Cost efficiency. Just one development team is required.
- Reduced time to the market. Testing, deployment, and update are quicker.
- Community support and reusable components’ access.
React Native will still be a trending framework for IOS and Android application development thanks to its almost-native performance. Companies like Airbnb, Tesla, Walmart, Bloomberg, Instagram, and new startups prefer it as their choice in mobile app development.
4. JavaScript API Architecture
GraphQL is regarded as the alternative for the REST APIs for 2019. This query language is lightweight and enables a software developer to make particular requests from the server. It simplifies packaging the particular requests eliminating the need to send further queries to obtain all the required resource properties. However, one needs to learn the language and lacks versioning.
5. JavaScript Application Rendering Framework
Next.js will trend in 2019 due to its minimalist JavaScript-based framework nature to render your app on the server side. This way the application content is generated, when doing a page, it already has all the needed content. It works out of the box with minimum code and learning curve enabling JavaScript to run on the server, desktop or mobile device without any complicated setup.
6. JavaScript UI Development Environment
Storybook.js is a tool launched for React applications specifically. The tool builds components in isolation and allows the creation of UI components without interference with the UI development. It is highly customizable to fit the needs of the team through add-ons, config, and the API reducing the development time.
7. JavaScript Testing Tools
Jest is more popular among the frameworks for automated testing of applications made with JavaScript. Jest is a complete and ready to set up JavaScript testing solution functioning out of the box for any React project. It conducts its tests in parallel raising the overall performance and is able to collect code coverage data from the entire project and the untested files. Jest is optimized to react quickly with no extra setup or libraries.
JavaScript ecosystem is a large set of integrated software frameworks, tools, libraries and packages with the final aim of making the software development solid and efficient. JavaScript has dominated the top popularity list of programming languages for over 6 years enabling dynamic and user-friendly websites and apps. Being easy to learn, robust and readily accessible, it is still evolving and soon we will see even further new improvements in the JavaScript world.
