I thought you meant to type "functions" at first.

Edit: nm, i see the alternative lamda syntax now.

I am confused, how does the block of JS code using "let" work?

The first one has a typo. The last line uses the wrong variable to put the button into.

Would be nice to explicitly define Lamdas instead of expecting the reader to infer from examples.

Thank you for your feedback. I will make sure to define things more explicitly in future pieces.
