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)!

Really good course, hope I can get content of this high quality in my own university. Programming language Theory is really beautiful.

This course presents a beautiful contrast between static and dynamic Type Systems. Week's 2 homework is challenging and rewarding.

If you really wanna get what programming languages are about, give this one a whirl! Great homework assignments and solid videos.

The latter half of this course is much harder than the former, but there are still knowledge I can understand. Next step, Part C

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

I've learned so much in doing this courses. I can not recommend them enough. Dan is a brilliant teacher too.

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

Worth your time for gaining a deeper insight of programming language. So challenging and intriguing!

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

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

Dan's class is absolutely fantastic! He explains concepts clearly, keeps the lessons engaging.

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!

Fairly tough assignments but a great course!!

Need more courses from Prof Dan Grossman.

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