We are done with Why-ideas, now we come further to the What for list.


JS for the front-end.

The first and foremost task of the JavaScript language is to make the web page interactive. JS works in a team with HTML and CSS on the front-end. HTML, which stands for HyperText Markup Language, is responsible for the structure and the content of the site, while CSS (Cascading Style Sheets) tackles the style. JavaScript creates all the fun. It makes everything dynamic. Here is a shortlist of what JS can do in the front-end:

  • show and hide information with a click

  • change the color of the button, when the mouse is on it

  • zoom images

  • create carousels and sliders

  • add animation

  • play audio and video on a page


JS for the back-end.

Here we deal with something invisible, also known as server-side. JS can be used together with tools like Node.js, for instance, to save data to a database, to process payments, to save posts, and so on.


JS for mobile development.

With the rapid development of smartphones, it is important to stay up-to-date. So, JavaScript can come in handy with developing apps for mobile devices. Various JS libraries and frameworks facilitate this process significantly. They offer a set of ready-made tools that can be used as bricks in the process of building an app. We will provide an example of such a library further.

Games created with JavaScript will not embody the masterpieces of complexity. But it is always fun and entertaining, especially when you are just gaining your experience in game development.
