First I'd like to thank you for your work. I've learned a lot from you and your teachings.

When it comes to "foo bar" examples, as a learner, I think it causes MORE cognitive load not less.

I think this is because, it's hard to make connections between meaningless words like foo, bar and baz

Conversely, most of the "aha" moments come from your ELI5-like explanations of concepts

The concept of a "promise" made sense to me when you used buying a hamburger at a fast food store in your workshop on asynchronous javascript.
