Industry Use-Cases
Front-End
There are three main components when it comes to front-end development: HTML, CSS, and JavaScript. HTML is the structure and content of the site, CSS (Cascading Style Sheets) makes it look pretty, and JavaScript is what powers its interactivity. It powers the site’s general interactivity and makes it possible to build rich UI components such as image sliders, pop-ups, site navigation mega menus, form validations, tabs, accordions, and much more. Various banner ads have chat support, suggest content, have formed or offers social sharing they are powered by a 3rd party JavaScript plugin.
Google of course uses JavaScript, whenever we start typing in the search box, it gives us suggestions. It’s all because of JavaScript. Nobody can ever imagine using the Internet without Google and the dynamic nature of Google is provided by JavaScript. Google is also the creator of one of the most popular front-end frameworks, Angular.
Back-End
Backend developers use a type of JavaScript called Node.js for backend work. The Node.js framework allows a developer to handle data updates from the front end and build scalable network applications able to process many simultaneous user requests, amongst other things. Node.js is the most popular backend framework; it is used in MERN, MEAN, and MEVN stacks.
