Great! A complement to Part A and it really uses things we've learned in Part A with the Standard ML language and does lots of comparisons, so you should probably take Part A if you have never used SML. Learned a lot with this course. Thanks!

An absolutely high quality class. The instruction is superb, the assignment is on par with top programs at Stanford, MIT, and CMU. Dr. Grossman's lecture is just so clear and energetic that makes learning this hard topic fun.

I didn't terribly care about racket because of some previous common lisp/scheme experience; I wish the static/dynamic typing comparison had more space, but that's just because to ME that was the most interesting part.

This course (as Part A and C) is great - Dan is great in teaching and the content is perfect for anyone who wants to learn more about programming languages!

Warning - you might end up loving FP :)

I took this course about 10 years off the college, and it was excellent refresher on the topics I don't use on a daily basis. Absolutely great lecturer, great videos and study materials!

Great course! Learned more about PL, what is interpreter/ compiler language, what is statically typed/ dynamically typed. The homework is very rewarding! Looking forward to Part C.

A strong follow-up to Part A. The second week's homework assignment is quite difficult, but very rewarding. This course has greatly helped shape my views on programming.

Excelent course.! Wished contained more material. Also I think changing the editor from Emacs to Dr Racket was not really necessary... all in all excellent course!

Just as good as the first segment of the course. Learned a lot of good material about dynamically vs statically typed languages and how languages are interpreted.

Very enjoyable course, follow-up to Part A. Building an interpreter really solidifies what we saw, a really nice exercise. I'll definitely move on to part C!

I'll learn many things in this course with the enthusiasm and hard work of a very knowledgeable professor on the field. Great course 10/10 would do it again.

This series is really the course you need to take if you feel not comfortable and want to know why(or describe the feelings) when you code in school or work.

s a very good introduction to functional programming in dynamic language by focusing on the fundamentals. Highly recommended!!

The course is really fantastic! It leads me to the world of Racket programming and guides me to many concepts in programming language theory (PLT).

Suitable even for experienced programmers.

Excellent presentation of fundamental programming concepts.

Exercises are challenging but rewarding.

The programming assignments are carefully designed such that without so much coding you can capture the essence of the idea. Highly recommend.

It's challenging as much as it is rewarding, and the peer review is a very nice arrangement for people to see how others are doing things!

Great follow-up to Part A, really builds on the concepts introduced there and tackles some quite complex topics (writing an interpreter)!

Awesome course, a lot of fun with really interesting exercises. The interpreter homework was both difficult and super rewarding.

A good introduction to dynamically typed language. I really the discussion about the static checking and dynamic checking.

Awesome course for programmer's interested in learning programming idioms or otherwise interested in language design

It's hard not to see how much time and energy is spent on this course by the instructor and the team!

Parenthesising expressions has never been more fun. And you get to implement your own Lisp dialect.

Lovely course! The treatment on closures was great, and I really enjoyed the programming exercise.

the best online course I've ever taken! expecting more courses from Dan and Washington University
