writing code isn't a tough thing as before, specially if you are using frameworks, that's why the developers community is becoming large by the time passing, but most of the developers don't write a clean code, it dramatically gets messy and they mostly stick to fat controllers/models, which makes the code harder to maintain, test and scale. by enrolling to this course, you will understand how to write code to the highest standards, that's open to maintainability, scalability, and it will be testable. also it won't be tough anymore to remember whatever logic you have written earlier and keep following your code to understand which case you are particularly at, as the code will follow the well known principles and patterns.
