JavaScript and it’s use cases
JavaScript makes webpages alive. When it was created initially had another name: “LiveScript”. JavaScript is completely different from Java. JS has its own specifications and it is independent language. It basically used more in frontend development and it enhance the code more when integrated with HTML and CSS. Webpages look more lively by adding it.
- HTML is the markup language that we use to structure and give meaning to our web content, for example defining paragraphs, headings, and data tables, or embedding images and videos on the page.
- CSS is a language of style rules that we use to apply styling to our HTML content, for example setting background colors and fonts, and laying out our content in multiple columns.
- JavaScript is a scripting language that enables you to create dynamically updating content, control multimedia, animate images, and pretty much everything else. (Okay, not everything, but it is amazing what you can achieve with a few lines of JavaScript code.)
JavaScript is the thirst most demanding web technology after HTML, CSS. Today there’s no website which doesn’t uses JavaScript and JavaScript Frameworks.
What are Frameworks of JavaScript?
JS Frameworks are the collections of JS code libraries that provide developers pre-written JS code which they use further for web development.
Most Used JavaScript Framework by Industries :
- AngularJS: Angular is a TypeScript-based open-source web application framework led by the Angular Team at Google and by a community of individuals and corporations. Angular is a complete rewrite from the same team that built AngularJS.
- ReactJS: React is an open-source front-end JavaScript library for building user interfaces or UI components. It is maintained by Facebook and a community of individual developers and companies. React can be used as a base in the development of single-page or mobile applications.
- NodeJS:Node.js is an open source, cross-platform runtime environment for developing server-side and networking applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.
Case Studies of Top MNCs using JS
NETFLIX:
We all know Netflix is leading company in entertainment industries. Netflix has a large audience . So when platform increases , so do their needs.
The core infrastructure is often not designed to handle these new challenges as it was optimized for a relatively simple task. Netflix, a member of the Opensource Foundation, had to overcome this challenge as it evolved from a massive web streaming service to a content production platform.
Netflix initially used Node.js to enable high volume web streaming to over 182 million subscribers. Their three goals with this early infrastructure was to provide observability (metrics), debuggability (diagnostic tools) and availability (service registration). The result was the NodeQuark infrastructure. An application gateway authenticates and routes requests to the NodeQuark service, which then communicates with APIs and formats responses that are sent back to the client.
Facebook:-
You’re probably aware that Facebook uses JavaScript. It’s kind of hard to miss. What’s probably not as obvious is exactly how much JavaScript goes into making Facebook and how much Facebook is involved in JavaScript development.
Try disabling JavaScript in your web browser and going to Facebook. The website will actually stop you from logging in because it won’t work without JavaScript.
You may have noticed the way that Facebook loads. Each piece of the page is separate. Facebook has invented its own way of breaking down and delivering sections of JavaScript separately. In an odd way, each section of your Facebook page is a collection of independent JavaScript applications.
It doesn’t stop there. Facebook created React, one of the most popular front-end frameworks. Facebook uses React on Facebook.com as well as Instagram and WhatsApp.
Many Top MNCs use JavaScript this blog can’t list all the MNCs, But more few are Walmart, Google, LinkedIn, eBay, Uber, Medium, GoDaddy, Mozilla, Groupon, etc.
Thankyou !
