11. WHY
12. WHY Has very little real world use
13. WHY Has very little real world use Is often very inefficient
14. WHY Has very little real world use Is often very inefficient Breaks all coding standards
15. WHY Has very little real world use Is often very inefficient Breaks all coding standards Creates unmaintainable code
16. WHY Has very little real world use Is often very inefficient Breaks all coding standards Creates unmaintainable code
17. WHY Has very little real world use Is often very inefficient Breaks all coding standards Creates unmaintainable code Will force you to have a deep understanding of the language
18. WHY Has very little real world use Is often very inefficient Breaks all coding standards Creates unmaintainable code Will force you to have a deep understanding of the language Make you a better coder
19. WHY Has very little real world use Is often very inefficient Breaks all coding standards Creates unmaintainable code Will force you to have a deep understanding of the language Make you a better coder Creative “Necessity is the mother of invention”
20. WHY Has very little real world use Is often very inefficient Breaks all coding standards Creates unmaintainable code Will force you to have a deep understanding of the language Make you a better coder Creative “Necessity is the mother of invention” Fun and addictive
