The first impressions when I started learning Clojure

1. there are a lot of brackets in Clojure, every time you want to use a function, a pair of brackets need to appear.

2. If there are other people who don't understand how to use fn and come from a Java background, there is a tip.

(map (fn [row] some code ) rows) is similar to rows.stream().map(row -> Some code).collect(Collectors.toList());

3. Similar to Python, Clojure also doesn't have explicit data types, and there are not "," between parameters.

4. Try to use more map, reduce, filter, etc., they are truly powerful.
