📌 Write a blog explaining the use-case of javascript in any of your favorite industries.

The collection of prewritten code that has some special working function in JavaScript is known as the JavaScript framework.

Examples:

  • Node.Js: Node.js is an open-source, server-side platform built on Google Chrome’s JavaScript Engine. The number of websites using NodeJS has crossed 84,000. It is one of the most downloaded, cross-platform runtime environments for executing JavaScript code.
  • Angular.Js: One of the most powerful, efficient, and open-source JavaScript frameworks is Angular. This framework is operated by Google and is used for developing Single Page Application (SPA). This development framework is known primarily because it gives developers the best conditions for combining JavaScript with HTML and CSS. Over half a million websites like google.com, youtube.com, etc. are using Angular.
  • React.Js: React is another JavaScript library maintained by Facebook for building interactive and complex UI. It is one of the most trending frameworks with over 3 lakh websites implementing React in their UI. To name a few websites, we have Microsoft.com, yahoo.com, and so on.

Every six months, a new JavaScript framework is born. The rate at which new frameworks pop up in JavaScript is quite alarming. You can find JavaScript frameworks everywhere and are used for just about everything. There’s even a constant urge to use frameworks for trivial things like printing “Hello World.”

A framework is a collection of components, libraries to be used for specific functionalities; they are usually extensible. Frameworks are also made up of reusable abstractions of code, that are usable through a well-defined Application Programming Interface (API).

So, a JavaScript framework is a framework written in JavaScript for use in a JavaScript runtime environment. There are lots of JavaScript frameworks out there for different purposes, such as creating user interfaces, building mobile apps, and so much more.

It is not always necessary to use a framework, but it’s one of the tools that can help you develop software better and faster. Frameworks will abstract some complexities away from you and let you focus on writing the business logic for the software, thereby saving development time.

With a framework, you won’t have to reinvent the wheel, as they are usually considered batteries included. Frameworks come with some of the standard tools you would need when writing code; for example, ExpressJS comes with a JSON parser.

A framework sometimes also enforces a pattern or standard to follow, which makes it easier to write better code with cleaner file structures.

Companies Using Node.js

  • Uber :

Uber has popularized the ‘on-demand economy model where quick accessibility is given prime importance. Uber is a prominent example of a sharing economy and after a huge success of this model, companies started uberization where mobile apps work as a mediator between service providers and clients. Uber has simplified transportation for every person and now offering more than just an on-demand taxi service. It offers services like vehicles for hire, food delivery, freight, couriers, package delivery, and vehicle rental services.

With over 110 million monthly active users worldwide, Uber is one of the largest providers in the gig economy. It carries out operations in over 900 cities worldwide.

Uber uses Node.js in its APIs, UberEats application, and almost much of its code written in Python, Node.js, Go, and Java. Uber’s API Gateway was one of the largest Node.js applications at Uber.

  • Netflix:

Hardly, there is a person who doesn’t know this name. Netflix is one of the amazingly popular over-the-top (OTT) platforms headquartered in California.

As of October 2020. Netflix had over 195 million paid subscriptions worldwide. It is one of the largest entertainment/media companies by market capitalization.

Netflix uses Node.js to handle high-volume streaming for millions of users. Architecture at Netflix is designed in a way that offers observability, debuggability, and availability. It is flexible, fast, and offers smooth performance — these are the key attractions of choosing Node.js at Netflix.

JavaScript benefits

  • Client-side execution of the logic brings faster user experiences. With the code running directly in the browser, the need for server calls is abstracted, hence a cut in loading times. Even with the presence of a server, the fact that JS is asynchronous means that it’s able to communicate with the server in the background without interrupting the user interaction taking place in the frontend.
  • Since the very beginning, JavaScript has brought user interface interactivity to the web. It now does the same for applications of all kinds, helping to develop the most engaging UX. Today, frameworks like Vue.js are bringing transitions & animations to the next level.
  • JavaScript is behind any good responsive web design. More and more, developers need to adapt their design across multiple browsers and devices. Combining HTML5, CSS3 & JavaScript, they can do so within a single codebase.
  • For developers, JS is easy to learn and fast to get into active development. Its syntax is easy and flexible for newcomers. It also simplifies the development of complex applications by enabling developers to simplify the app’s composition. The many frameworks & packages out there also ease the life of developers to some extent.
  • If you haven’t got this yet, JavaScript is insanely popular. If popularity doesn’t always equal quality in life in general, it at least means one important thing: you’ll find the solution to any problem within the community. In web development, that’s not a negligible detail. If you’re someone that needs to hire developers, that’s also a big plus, as the pool of candidates is huge.

JavaScript is ever-evolving, and so is its ecosystem. I personally think the future begins with fewer new tools being created and the big players getting more mature and gaining major adoption. We’re already observing this in the field of JS frameworks, where React and Vue.js are taking the edge. Same at other levels where tools are built on these frameworks. Gatsby, Next.js & Nuxt are slowly becoming the leading static site & PWA generators.

TypeScript will probably play a big part in what’s to come as well. This superset of JavaScript is being adopted massively by the community because it allows JS to scale better. The future holds many things in the tech world that will no doubt have an influence on frontend development, such as Artificial Intelligence or the Internet-of-Things. JavaScript will have to adapt to these new realities.

Thank You…
