On my rode to becoming a coding guru, I’ve decided to learn Haskell. This will be my first time learning a functional language and it’s been a pretty interesting experience so far. In functional programming variables are immutable, which means when a variable has been set to a certain value it can’t be changed to something else. To someone who has programmed in mostly C like languages this feels like a handicap, but it starts to make things interesting. It takes a little more time to think of a solution to a problem, but it’s fun.
Some example code of Haskell is below. The first function is fibonacci and takes a single number as an argument. The second function is factorial and only takes a single number as an argument. If you look at the factorial function, which is not the best implementation, it seems to define factorial in two ways, which is pretty awesome.
