Self-similar: a versatile folder pattern for code

“The word 'isomorphism' applies when two complex structures can be mapped onto each other, in such a way that to each part of one structure there is a corresponding part in the other structure, where "corresponding" means that the two part play similar roles in their respective structures.” – Douglas HOFSTADTER Gödel, Escher, Bach • Meaning and Form in Mathematics • pp. 57 I've seen various trends come and go in code folder and file structure. The two big ones in the front-end space seem to have
