Functional Programming

In the course Functional Programming the basic principles of functional programming are discussed and illustrated with examples.

Intro Functional Programming

The course starts with a discussion of the background of functional programming in the lambda calculus. In the functional programming paradigm a program is built from functions that perform operations on the arguments.

Functional Characteristics

Modern languages ​​such as Java, Python, Scala and JavaScript are equipped with functional features but are not entirely based on them.

Pure Functional Languages​​

Programming languages ​​based entirely on this paradigm are Erlang, F♯, Haskell, Lisp and ML.

Side Effects

The course covers how functions do not cause side effects in purely functional programming languages. These are effects that affect more than the result of the function, such as changing a global variable. Variables that serve as an accumulator, counter or control variable have no place in a functional language.

Map and Reduce

Also attention is paid to characteristic functional concepts such as immutable data, clojures and map and reduce algorithms.

Functions and Style

Additionally the course Functional Programming covers the various types of functions such as first class functions, higher order functions and lambda functions.

Other Functional Concepts

Finally the discussion of other functional terms such as Generators and Iterators, Fold Expressions, Memoization and Monads is on the agenda.

Audience Functional Programming Course

The course Functional Programming is designed for individuals who want to learn the principles of functional programming and to apply this knowledge in languages with functional aspects.

Prerequisites Course Functional Programming

To participate in this course experience with software development and basic programming skills are required.

Realization Training Functional Programming

The theory is discussed on the basis of presentations. Demos are used to clarify the concepts. Examples in different languages are used to illustrate the concepts. The theory is interspersed with exercises.

Certification Functional Programming

Participants receive an official certificate Functional Programming after successful completion of the course.
