Thank you for creating CodePen.

Others have mentioned, it already but I feel like I must echo the same sentiment.

I finished a 4 years CS degree years ago and I can honestly say that throughout my career I never had to create a linked list by hand.

Quiet frankly, knowing how to implement a heap with your eyes closed doesn't mean anything.

Running a successful SAAS for many years and scaling it on the other hand, is far more of an impressive accomplishment.

Kudos to you.
