:D. Why is anyone even considering FP vs OO programming a choice? I've used functional patterns within OO before and I'm sure the opposite is possible. Both ha

:D. Why is anyone even considering FP vs OO programming a choice? I've used functional patterns within OO before and I'm sure the opposite is possible. Both have merit depending on the skill-set and staff available to you, scale of project and existing infrastructure. I was however very disappointed when the author bundled interfaces into the mix as if it was the same as the rest of it. The interface enables you to support many different types of behaviour and enables you to structure your libraries in different ways. It's a different aspect from just classes themselves. Genuinely I don't think shit like this is healthy. Smacks of religion.
