The whole process is divided into two parts. Front End, and Back End.
However these days the desirability is all about artificial intelligence so its not the cutting edge any more.
It is the same with software engineering, C++, C#, Python, all are being augmented with artificial intelligence.
So the industry is moving into artificial intelligence.
But in the mean time so if you want to spend the time learning how to build websites perhaps its best to understand all of the activities involved.
Front end development, is essentially what it looks like to the end user of the website, whether that is on mobile phone, desktop, laptop, console, 4k television or even smart watch !
The back end is usually business services. and infrastructure services. This is were all of the essential products and services is kept. On the server.
SO throughout the evolution of the whole computers and networks we historically arrive at the now, which is ai, robots, drones, 3d printing, cryptos, nfts.
