O'Haskell is an object-oriented, concurrent extension of the functional programming language Haskell. Object-oriented programming (OOP is a Programming paradigm that uses " objects " and their interactions to design applications and computer programs Concurrent computing is the concurrent (simultaneous execution of multiple interacting computational tasks In Computer science, functional programming is a Programming paradigm that treats Computation as the evaluation of mathematical functions and A programming language is an Artificial language that can be used to write programs which control the behavior of a machine particularly a Computer. Haskell is a standardized Purely functional Programming language with non-strict semantics, named after the Logician Haskell Curry [1] It was developed at Oregon Graduate Institute and Chalmers University of Technology. The OGI School of Science and Engineering, located in Hillsboro, Oregon, United States is one of the four schools of the Oregon Health and Science Chalmers University of Technology or Chalmers tekniska Högskola ( CTH) often Chalmers, is a University in Gothenburg, Several features of O'Haskell have been adopted in the Timber programming language. Timber is a functional Programming language descendant from O'Haskell, targeted at embedded real-time systems [2]
