  • Level: Intermediate Level
  • Time: Approximately 30 hours to complete (Suggested pace of 2 hours/week)
  • Language: English
  • Subtitles: Arabic, French, Portuguese (European), Italian, Vietnamese, German, Russian, English, Spanish.

This course covers the fundamental concepts of programming languages, with a focus on functional programming. In all spheres, the course uses the languages ML, Racket, and Ruby to demonstrate the ideas, but the true goal is to teach you enough about how any language “fits together” so that you can program more effectively in any language — and learn new ones.

Also, this course will provide you with a framework for understanding how to use language constructs effectively and how to develop proper and elegant programs. It will not be overly theoretical or focused on programming specifics. 

You will learn to think more deeply by employing several languages rather than thinking in terms of a single language’s grammar. 

Equally, learning how to construct durable, reusable, composable, and elegant programs requires a strong focus on functional programming. Indeed, functional programming is the source of many of the most fundamental concepts in modern languages. 

Prepare to discover a new and attractive way to look at software, as well as how to have fun creating it.

The course presupposes some prior programming knowledge, which is detailed in the first lesson.

Part A, Part B, and Part C are the three Coursera courses that make up the course. The whole course involves a large amount of tough information, as detailed in more detail in the first module of Part A, therefore the three-part arrangement provides two intermediate milestones and opportunities for a rest before continuing.
