you described the languages ​​used by the "web developer", but did not specify what he does, again "Mobile application developers" - you also only listed the languages. Too many general phrases, too few specific descriptions. When you describe the requirements for programmers, you write as if the professor must know the alphabet. The main question, as everyone has not revealed. The text is very difficult to read. I wonder what you wanted to say about prime zero here? "understanding of prime zero is essential"
The main question, like the majority, was completely misunderstood. In the next lesson, there will be less text and more practical. Good luck.
