Frequently asked questions

What is the difference between the front end and the back end?

The front end runs on the visitor's device and handles everything they see and click. The back end runs on a server and handles stored data, accounts, payments and business rules. The two communicate over the network, usually by sending requests and receiving data in reply.

Which languages are used for front-end work?

HTML for structure, CSS for presentation and JavaScript for behaviour are the three that browsers run directly. Frameworks and build tools are layered on top of them, but they all end up as those three.

What does full stack mean?

It describes someone who works on both the front end and the back end rather than specialising in one. It is a description of range, not a separate technology.
