Should (prn my-map) be doing a pretty print in console? mine doesn't...

Hi, I have cljs-devtools installed, I get the notification in the console that `:formatters` is active, and I sometimes see colored, formatted clojure data structures, but I was hoping that when I do `(prn my-map)` within some cljs source file, that would justify and color a large map. I'm just getting a regular print of the datastructure in the console, same as when cljs-devtools is not active. Am I doing something wrong? Thanks.

先从 cljs-devtools formatter 的设置和 `:formatters` 入口点开始，然后在控制台中从 ClojureScript 源文件复现 `(prn my-map)`。确定此调用是否应产生带颜色的格式化输出，并识别应记录在文档中或加以修正的行为。
