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.

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.

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.

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)!

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!

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

Great course to learn dynamic typed language, and implemented a interpreter on a small language.

The assignment is challenging. This course gives a very good idea of how an interpreter works.

Better than the first one has we get more into the theory which is super useful!:)

Thanks Dan!

I really enjoy the course and like how Dan explains everything. Very thoroughly and clear!

Very interesting and challenging course. One of the best courses on Cousera, for sure.

excellent! vey helpful for ungraduates and programmer! need time to understand truly.

One of the Best course I have ever taken. A great many of concrete examples. Thanks!

It is great fun to learn Racket and use it to implement an interpreter for MUPL.

Amazing course!!! Excellent lecturer!! Really learn a lot of PL and Racket.
