- [Instructor] The second main concept of functional programming is the separation of data and functions. And this is a case where functional programming is directly in contrast with object-oriented programming, where data and functions are almost always grouped together. Let's see what the separation of data and functions looks like. So, first of all, for our purposes, data might be any values that a program contains. That could be employee info in a payroll program, for example, or information about cars on a used car website, or it could be data about characters in a video game. It could be anything really, all of this is data.
