Function composition is one the key features (among others) of functional programming. Programming languages that offer higher order functions as a feature can potentially use function composition.

Coursera Functional Programming has not been my first experience in an online course, but it has been the most satisfying by far. Many people were interested in it, and I think it created a great hype, not only in the course forums but in social networks like twitter. People all around the world were interacting in the same course, creating really interesting conversations and discussions about the subject. Really nice.
