在Clojure中访问嵌套地图值的方法？

Question

I am currently using the two following blocks of code to access nested values in ClojureScript: 我目前正在使用以下两个代码块来访问ClojureScript中的嵌套值：

  (def response (re-frame/subscribe [::subs/quote]))
  (def body (:body @response))
  (def value (:value body))
  (println value)

  (def result (-> @(re-frame/subscribe [::subs/quote]) :body :value))
  (println result)

 (def lol (get-in @(re-frame/subscribe [::subs/quote]) [:body :value]))
 (println lol)

Are there any better / more succinct ways of doing this? 有没有更好/更简洁的方法？ Thanks. 谢谢。

Answer 1

Keys can be used as operators to retrieve its value like so: 可以将键用作操作符来检索其值，如下所示：

(def lol (:value (:body @(re-frame/subscribe [::subs/quote]))))
(println lol)

However, I prefer the verbose way using a function as get-in 不过，我更喜欢使用功能的详细方式get-in
