haskell how to import module

A Haskell program is a collection of modules where the main module loads up the other modules … In Haskell, program subcomponents are divided into modules. Haskell is a functional language and everything is denoted as an expression, hence a Module can be called as a collection of similar or related types of functions. Each module sits in its own file and the name of the module should match the name of the file (without the ".hs" extension, of course), if you wish to ever use that module in a larger program. Similarly, Haskell can be considered as a collection of modules. You can import a function from one module into another module.
