#1 best-selling book in functional computer programming (Java/OOP to FP)

Many weeks after its release, my new book — Learn Functional Programming Without Fear — is still a #1 best-selling functional computer programming book on Amazon.com, as of December, 2022. I hope it will be a great Christmas/Holiday 2022 book gift for the computer geek in your life!
