Use cases of Javascript …
Why we should use javascript ?
JavaScript is a scripting or programming language that allows you to complex features on web page every time a web page does more than just sit there and display static information for you to look at displaying timely content updates, interactive maps, animated 2D/3D graphics, scrolling video jukeboxes, etc. you can bet that JavaScript is probably involved. It is the third layer of the layer cake of standard web \technologies, two of which (html and css) we have covered in much more detail in other parts of the Learning Area.
What is JavaScript?
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 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:
1) Adding interactive behavior to web pages :-
JavaScript allows users to interact with web pages.
a)Show or hide more information with the click of a button
b)Change the color of a button when the mouse hovers over it
c)Slide through a carousel of images on the homepage
d)Zooming in or zooming out on an image
e)Displaying a timer or count-down on a website
f)Playing audio and video in a web page
g)Displaying animations
h)Using a drop-down hamburger menu
2) Creating web and mobile apps
Developers can use various JavaScript frameworks for developing and building web and mobile apps. JavaScript frameworks are collections of JavaScript code libraries that provide developers with pre-written code to use for routine programming features and tasks — literally a framework to build websites or web applications around.
Popular JavaScript front-end frameworks include React, React Native, Angular, and Vue. 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!
3)Building web servers and developing server applications
Beyond websites and apps, developers can also use JavaScript to build simple web servers and develop the back-end infrastructure using Node.js.
