A few months ago I worked through the book Web Development with Clojure, 2nd Edition. The book was written in 2016 and some code is outdated. That was frustrating but I could get it to work by looking up the documentation for Luminus and googling everything else. When I tried to start another project today, I got tons of errors from the nrepl. And I have no clue if it's related to VSCode, Luminus, Clojure, leiningen or whatever tool I use.
Here is one of the Algorithm challenges from FreeCodeCamp: Intermediate Algorithm Scripting: Sum All Odd Fibonacci Numbers: Given a positive integer num, return the sum of all odd Fibonacci numbers that are less than or equal to num. The first two numbers in the Fibonacci sequence are 1 and 1. Every additional number in the sequence is the sum of the two previous numbers. The first six numbers of the Fibonacci sequence are 1, 1, 2, 3, 5 and 8.
