Heard about object-oriented programming, but not sure what it is? Object-oriented programming (OOP) is a popular style of programming. It comes up in technical interviews often and it's an essential skill for every developer. The problem is that there’s lots of bad info out there about OOP. Lots of myths, misconceptions, bad advice and downright poor tutorials and books. It took me a long time to really get it!
