The JS Ecosystem Just Got Better and More Powerful: JavaScript Trends in 2019


In survey after survey, JavaScript’s popularity as a programming language continues unabated, and 2018 is no exception. Ask developers what makes JavaScript popular and you’ll get a tongue-in-cheek response that JS is like oxygen; people need not acknowledge its existence, but they can’t do without it. Just consider three significant benefits that JS programmers enjoy.  

JavaScript is the Last Word in Cost Savings

JS is free and it’s open source, and when developers use its array of libraries, frameworks, and tools they’re able to build, customize, and deploy applications faster and with considerable cost savings.

JS Provides an Efficient Framework

With JS you don’t waste time writing code from planet Earth to the Moon; the framework already exists – you can access patterns of reusable designs, and functions that perform tasks with greater clarity. Result: greater efficiency.

JS Ensures a Safer Ecosystem

You’ll see top JS frameworks prioritizing security, and you benefit by accessing a community of millions of developers that help you solve issues.

In an attempt to make the development process simpler, faster, and efficient, tools and platforms are undergoing continuous innovation, improvement, and integration, and nowhere is this more apparent than in the JavaScript ecosystem.

So, if you’re a developer arming yourself with reliable, robust and secure toolkits for 2018 and beyond, here’s a peek at what JavaScript promises for web and mobile applications development.

Hit the Ground Running With Front-End Development Frameworks for New Websites

Asking React and AngularJS developers which is better is like asking cat lovers and dog lovers which is the better pet. You’re handling powerful frameworks that are backed by the world’s biggest companies. Google, Forbes, and Weather are three biggies that swear by Angular as a front-end developing platform. React is sustained by Facebook and many other companies like PayPal, Airbnb, and Uber for front-end development.

Though the popularity of Angular remains undiminished, React was rated as the most popular framework in 2017. It became a triangular battle with the arrival of Vue.js (2014) which created waves when it was adopted by Expedia, the travel technology company, and GitLab, the web repository powering the DevOps lifecycle.

Let’s examine how the Angular, React, Vue.js sweepstakes is building up. Though Angular remains the all-in-one solution, React, and Vue.js have stolen a slender lead because of their flexibility in accepting external libraries. Though Angular and React are the heavyweights boasting a broader spectrum of tools, Vue.js is a comparatively lightweight option that’s easier to learn and delivers exactly what you expect it to.

So, 2018 will probably see Angular holding the fort against invaders while React gathers increasing support, and Vue.js gives both biggies a run for their money.  We’ll see developers choosing to handle larger more complex applications using Angular, but if flexibility is the need of the hour, there’ll be a bee-line for React and Vue.js.  

Trends in Back-End Development Framework That Are Creating Amazing Websites

In an environment where you do web application development, the back-end framework equips you with the tools and languages helping you tackle server-side programming. The mark of success in back-end development is measured by your knowledge of new databases, your appreciation of server architecture, the learning new languages, and of choosing the right stack. Selecting the right back-end framework involves a better appreciation of ease-of-use, speed, organized documentation, and community support.


Without the shred of a doubt, Node.js is the most in-demand framework in 2018, and this is confirmed by Stack Owerflow developer surveys.

When performance and speed are critical factors, Node.js pips in with valuable support. What makes the framework popular is the scalability of web applications that one can develop.

Scalability is crucial when you are dealing with data-heavy applications that survive on real-time messaging and ecommerce applications where speed is essential in boosting customer satisfaction, user experience, and conversion.

A startup couldn’t ask for a better tool than Node.js to put together a stack to spur peak performance from the word go. It’s easy, it’s simple, and you’ll be breezing through the protocols to your test-ready application without wasting a second.

Even with its apparent advantages, Node.js is undergoing constant innovation and is likely to hold its ground in 2018 and beyond. With colossal community support, Node.js comes across as a reliably robust back-end framework that is quietly efficient and has all the bells and whistles for secure applications development. Any doubts can be set to rest because LinkedIn and eBay are using this framework extensively.

Cross-Platform Mobile App Development Framework Is Seeing Great Enterprise Tools Coming to the Fore

The arena of mobile app development is witnessing fever-pitch excitement, and with Android and iOS dominating this space, you’ll need tools that work across these two pillars.  You could develop OS and device-specific apps natively, or use Facebook’s React Native to build apps that work on both platforms.

React Native continues to impact mobile app development in 2018, extending three significant benefits:

A Single Language Does the Job

It’s cost-effective using just one language – JavaScript to power applications that run on both Android and iOS, whereas native development would require skills in Java (for Android) and Swift/Objective-C (for iOS).

You Penetrate the Market Faster

It’s more advantageous for developing, testing, and deploying a single application that can be launched faster than if you were tackling each OS differently.

Strong Community Support and Reusable Components

It’s easier to locate and leverage community support and components that power faster app development.

So long as your work isn’t too complicated and you have good skill sets in JavaScript, React Native should be the undisputed choice.

But React Native Does Lag Behind in Certain Areas

Lack of API and third-party library support will place hurdles in the path of more integrated app development. Of course, this defect can be overcome through embedding using native languages, but that approach ruins the single language approach.

If you’re seriously into augmented reality and virtual reality that are technology intensive and complicated, you’re better off trying native development which promises easier delivery wedded to excellent performance.

API Architecture Management Trends That Are Creating Ripples in 2018

GraphQL, since it debuted in 2015, has become the byword in API architecture and is quickly dominating the landscape in 2018. In the previous era, REST APIs were lording this space. The problem with REST was that when you made a resource request, you received everything including components that you don’t require. If a resource was unavailable, you had to make another request. GraphQL solves the data over-fetching and under-fetching problems endemic to REST.

GraphQL delivers precisely what you order, nothing less, and nothing irrelevant to your development agenda. You gain access to all the properties that you need, and there’s no ground for making additional requests. So you end up with a lighter load that’s faster and doesn’t slow down the network.

A Word About GraphQL Negatives

Developers need to dig deeper into their reserves of patience because GraphQL demands that you follow a steeper learning curve.

When you make API design errors that need to be reversed, or you’re making changes for any other reason, you’ll hit the hurdle of GraphQL lack of versioning. The only solution is to deprecate the old field and create a new field with new nomenclature. If you continue adding up such changes you could end up compromising the quality of the API which degrades over time.

What’s Hot and Exciting About Application Rendering Frameworks in 2018

React specific application rendering becomes possible with Next.js, a JavaScript framework for the server side. So, when you download pages, the content is already there. Next.js scores brownie points because it’s uncomplicated and faster, and there’s the additional advantage of having your content SEO optimized across major search engines like Google, Baidu, and Bing.  

A note of caution is that server-side rendering is going to be resource hungry, so that could strain your budget a bit. Although you’ll see app performance improving, if you happen to be data heavy, pages could load slowly compromising user experience.

The UI Development Environment trend That’s Defining 2018

In the category of User Interface (UI) development, nothing has captured the imagination of developers as much as Storybook, launched in 2016 by the Sri Lankan startup, Kadira.  Developers working on React applications are elated because Storybook enables developing and testing of UI components outside the application. This implies that components can be tested without unduly affecting app development, and in a faster way, paving the way for a quicker release in the market.

Automated Testing Tools Trending in 2018

The best of apps needs a solid test drive to gauge its effectiveness before deploying it in the market. One of the most popular JavaScript-based testing tools is Jest. It’s an automated testing framework that works really well on applications created using React.  

For sheer ease in out-of-the-box setup and use Jest is hard to beat, and because tests can be run in parallel, you can gauge overall performance more efficiently. Besides, Jest can be used to test only changes that you have made and that spares you the time and monotony of having to review the whole application.

The out-of-the-box testing compatibility and readiness of Jest makes it a must-have tool for writing cleaner, bug-free code that performs better.


The universe of JavaScript tools is abundant and ever-changing, and what we have put together is only the tip of the iceberg testifying to the effectiveness of JavaScript as the most sought-after tool in a developer’s arsenal.

In 2018 and beyond, you will see more changes as JavaScript evolves with developers needs to build a full technology stack for web development. Most of all, you can take pride in being a cog in an enormous wheel which is the JavaScript community – one that offers tremendous support at every stage of web development. If you aim to build robust, efficient, and reliable applications, your search for the technology enabler ends with JavaScript.
