Types of Haskell Programming Languages

Haskell is a statically typed, purely functional programming language. This means that the types of all expressions are known at compile time, and that all functions are defined in terms of other functions. Haskell has a rich type system, which allows for a great deal of expressiveness and flexibility.

There are two main types of Haskell:

• Standard Haskell is the most widely used version of Haskell. It is defined by the Haskell 98 standard, and is implemented by a number of different compilers, including GHC, Hugs, and Darjeeling.
• GHC Haskell is a dialect of Haskell that is implemented by the GHC compiler. GHC Haskell includes a number of extensions to the standard Haskell language, such as type classes, monads, and the IO monad.

In addition to these two main types, there are a number of other Haskell dialects, including:

• Generic Haskell is a version of Haskell with type system support for generic programming.
• Hume is a strict functional language for embedded systems based on processes as stateless automata over a sort of tuples of one element mailbox channels where the state is kept by feedback into the mailboxes, and a mapping description from outputs to channels as box wiring, with a Haskell-like expression language and syntax.
• Quipper is a Haskell dialect that is designed for writing efficient code.

The choice of which Haskell dialect to use depends on the specific needs of the project. For most projects, Standard Haskell or GHC Haskell will be sufficient. However, if you need the features of a specific dialect, then you can choose that dialect.

Here is a table that summarizes the different types of Haskell:
