Define list? What are the ways to create a list in Haskell?

 A list is a single linked list like one looks in an imperative language, but there is one major important difference. Only and the only operation we have is to put a node at the start of the list. We cannot change any values within a list, including the pointers from one list node to another.

Usage of square brackets can create a list in Haskell with commas, which separates the list’s values. There are only four functions, which are normally required, but because lists are so widely used in Haskell programs, the prelude provides various another functions also.
