Lambda (λ) Calculus Primer

A primer on the lambda calculus with the aim of giving a basic understanding of the theoretical underpinnings of functional programming.
Contents:
1. What is the lambda calculus?
2. Defining a function as a lambda abstraction
3. The simple untyped lambda calculus
4. Evaluation rules
5. Normal form and reduction orders

Thanks for this, explains it very well

[@valentinussofa4135]

I love how you explain about Beta-reduction very clear. Thank you so much. By the way I love Haskell. So I subscribed this channel and I hope I can learn more about Haskell through this channel. 🙏

This video is great! Appreciate it a lot

[@neilclay5835]

Incredible tutorial.

[@tanchienhao]

Nice video

[@gustavocruz988]

Great video !

Thanks for the video... Although the use of parenthesis helps to clarify things, it confuses me a little since there are no rule BNF rule for use of parenthesis in 6:24

[@programvydas5379]

Very well explained, thank you

Cristal clear introduction to Lambda Calculus

The content was well done, but I have some feedback on how the video was edited. I may be more photosensitive than the average person, but around 3:35, and for most of the rest of the video, when you were highlighting stuff the end effect of how you did it was to flash almost the entire screen several times per minute from light to dark and back. Some of the latter transitions started doing a fade, which helped, but the rapid flashing of the whole screen like that made the video hard to watch.

Haskell doesn't reduce to normal form, it reduces to weak head normal firm

TIL the creator of lambda calculus died in a town 30 minutes from me

[@user-tx4wj7qk4t]

Your eta reduction is incorrect. The 1 would be the second argument

Free means that a variable in the body has none in the head, not what you're trying to say here.
