JavaScript and How javaScript is used in different Industries ?
What is JavaScript ?
JavaScript is a high-level ,interpreted, object-oriented Programming language. It is one of core of the web technologies along HTML and CSS.
JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make web pages interactive. Where HTML and CSS are languages that give structure and style to web pages, JavaScript gives web pages interactive elements that engage a user.
Common examples of JavaScript that you might use every day include the search box on Amazon, a news recap video embedded on The New York Times, or refreshing your Twitter feed.
JavaScript is used for developing : -
- Client-Side Web Applications
- Server-Side Web Applications
- Mobile Applications
- Desktop Applications
- Web Games
JavaScript is mainly used for web-based applications and web browsers. But JavaScript is also used beyond the Web in software, servers and embedded hardware controls. Here are some basic things JavaScript is used for:
-> Adding interactive behavior to web pages
JavaScript allows users to interact with web pages. There are almost no limits to the things you can do with JavaScript on a web page.
these are just a few examples:
- Show or hide more information with the click of a button
- Change the color of a button when the mouse hovers over it
- Slide through a carousel of images on the homepage
- Zooming in or zooming out on an image
- Displaying a timer or count-down on a website
like this many more.
-> Creating web and mobile apps using javascript
Today, Most of web apps are developing using javascript and javascript’s framework .
JavaScript frameworks are collections of JavaScript code libraries that provide developers with pre-written code to use for routine programming features and tasks .
These are popular JavaScript front-end frameworks include ReactJs, React Native, AngularJs, and VueJs and many more.. Many companies use Node.js, a JavaScript runtime environment built on Google Chrome’s JavaScript V8 engine. A few famous examples include Paypal, LinkedIn, Netflix, and Uber!.
Company which are using javascript:
These are major companies who are using js Microsoft, PayPal, Netflix, google, ebay, walmart, linkedlin and many more .
Linkedlin :
LinkedIn is the world’s largest professional network on the internet. You can use LinkedIn to find the right job or internship, connect and strengthen professional relationships, and learn the skills you need to succeed in your career. You can access LinkedIn from a desktop, LinkedIn mobile app, mobile web experience, or the LinkedIn Lite Android mobile app.
LinkedIn relies on NodeJS for its mobile site. A few years back, LinkedIn used Rails for its mobile site. As with other other large Rails applications, it was slow, monolithic, and it scaled poorly.
LinkedIn switched over to NodeJS to solve its scaling problems. Node’s asynchronous capabilities allowed the LinkedIn mobile site to perform more quickly than before while using fewer resources. Node also made data sharing and building APIs easier for the LinkedIn developers.
eBay:
eBay’s story is a lot like Netflix’s. For a long time, just about everything in eBay’s tech stack was based on Java. A few years ago, eBay encountered a problem that Java wasn’t the right solution for. They decided to give NodeJS a shot instead.
Node worked so well that eBay not only kept using it for that particular service, they began migrating their entire user facing stack to NodeJS. Now, just about everything that you interact with on eBay is powered by Node. Sure, beneath Node, Java is still dealing with their databases, but eBay still places a lot of trust in NodeJS.
javaScript is used in Artificial Intelligence nowadays.
TensorFlow.js is an open source software library for JavaScript developers to create and use machine learning or deep learning models directly in the browser or a Node.js application. TensorFlow is the broader open source software that includes support for different programming languages such as Python and different platforms such as server, mobile, and IoT.
Conclusion:
JavaScript is one of the top programming languages out there today. This is easy to see as there is a constant release of new libraries and frameworks for the language. While a lot of these frameworks are for the web, there are a couple that makes JavaScript usable in different fields.
A decade ago, using JavaScript for Artificial Intelligence or Mobile Apps would have been laughable. But the story has changed. In summary, there are many different uses of JavaScript, and that list will only get longer.
