I'm a CS graduate from poor and underdeveloped country so my education might not be upto the standard so pardon me for that.
I'm planning to learn full stack web development for job. Be it MEAN, MERN, python django sqlite etc
I want a "URL shortener", it's built already. That too in form of tutorials. There are codes around the internet telling how to do each part of this system. Most actually only write codes in their tutorials and not make tutorials independent of code.
How do I build something without looking at other's code? For eg: I want to build a "URL shortner", where can I learn about "URL Shortener" system independent of code.
"URL Shortner" is just an example. The software could be anything.
