Best Functional programming Videos
The 225 Functional programming videos here were recommended by different people across different months. Choose by who it is for: 24 introductory, 137 intermediate, 18 for a general viewer, and 46 for someone who wants the harder derivation. Most of them are a talk. What they share is that one speaker finishes a claim, and the examples exist to hold that claim up. Channels you will keep seeing include ClojureTV, Strange Loop Conference, Google TechTalks.
