Welcome to the Haskell page! Here, you'll find a description of the language as well as a list of sample programs in that language.
With sixteen of these tutorials already out of the way, it will probably come as no surprise that I took to Wikipedia to learn more about Haskell.
As stated already, Haskell is a general-purpose functional programming language that first appeared in 1990. Despite its relatively old age, Haskell is still maintained. In fact, the latest standard was developed back in 2010. By 2020, a new update should be available.
In terms of features, Haskell supports strong, static typing, pattern matching, lazy evaluation, and even list comprehensions. To be honest, this is the first time I'm hearing about lazy evaluation, so I figured I'd dig into that a bit.
As it turns out, lazy evaluation is a technique which defers computation of a functions input until the value is needed. In other words, expressions are only evaluated when they are needed. If my explanation is bad, take a look at the article I linked above. It covers the concept in great depth.
At any rate, I think that's plenty of background for now.
