What is the difference between a front-end and a back-end developer?

Question

I never really understood the difference. Thx in advance!

Answer 1

Well let's take SoloLearn as an example, the mobile or web app we are using refers to front-end which directly interact with end-users.

On the other hand, back-end refers to a separate layer which serves the front-end and contain most core business logic. For example, quiz/lesson approval process, daily global rank or selection of daily highlights.

In addition, it's common to refer this anology to a restaurant. What we see/deal with (order with waiter) is the front-end while what we don't see (food preparation in kitchen) refers to back-end.

Clear as crystal or mud? 😉

Answer 2

front-end is what users see like the design of a website or an app... backend is what's behind it like how is the app running? why does the button do what it does? etc. etc.

Answer 3

Crystal.

Answer 4

And How does One Build these Back ends???
