The Computer Science Departments of many universities teach a functional language as the first programming language. Using a functional language with its high level of abstraction helps to emphasize the principles of programming. Functional programming is only one of the paradigms with which a student should be acquainted. Imperative, Concurrent, Object-Oriented, and Logic programming are also important. Depending on the problem to be solved, one of the paradigms will be chosen as the most natural paradigm for that problem.
