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.

I agree with this, foo/bar/baz stuff is abstract and means nothing. This means the learner need stop associate something they don't know with nothing which is really hard. An analogy of something the learner knows is way easier to grasp..
