Sass section seems wonky

A really specific question:
what is the difference for the two examples in the beginning of this lesson:|

Also what is a map in CSS? It sounds sorta like an array?

Just my opinion, but the Sass section seems to need more attention from a writer. It’s been the hardest to follow out of all the classes I’ve taken here on FCC so far, and I’ve done the JavaScript section.

Actually a list in Sass is like a JavaScript array. Where, a map in Sass is like a JavaScript object with key/value pairs.

Ahhh, an array and an associative array. Thanks.
