omg, haha! I honestly never expected anyone to actually read them so this feedback is awesome to hear. <3 Thank you! I've moved on to focusing on LeetCodes nowadays and I do try to document my process as much as I can on there. I go by the same handle there if you're interested! :) Again, thanks for the encouragement—I'm glad I could help!

Glad you enjoyed it!

You can't compare arrays like that in JavaScript. If a and b are arrays, but aren't referring to the same object (array), a == b will always return false.
