Summary of book "Clean Architecture" by Robert C. Martin

Uncle Bob, the well known author of Clean Code, is coming back to us with a new book called Clean Architecture which wants to take a larger view on how to create software.

Even if Clean Code is one of the major book around OOP and code design (mainly by presenting the SOLID principles), I was not totally impressed by the book.

Clean Architecture leaves me with the same feeling, even if it's pushing the development world to do better, has some good stories and present robust principles to build software.

The book is build around 34 chapters organised in chapters.

	You can use docker standart volumes too.

	The parser below is a predictive, recursive-descent parser. The use of a predictive parser
	is possible because JSON has an LL(k) grammar. Specifically, JSON has an LL(1) grammar,
	a fact that is hinted at in the `parse_json` function: `parse_json` looks ahead by only
	one character (not even a whole JSON token) in order to decide how to parse the string.
