Functional programming is a programming paradigm: a different way of thinking about programs than the mainstream, imperative paradigm you$$re probably used to$.$ For this reason, learning to think functionally is challenging but also very enriching. My ambition is that by attending this course, you$$ll never look at code with the same eyes as before!

The learning process can be a bumpy ride. You$$re likely to go from frustration at concepts that seem obscure or useless to exhilaration when something clicks in your mind.

Why are functions important?
