clojure map values

What is a map in Clojure?
Maps are represented as alternating keys and values surrounded by { and }. When Clojure prints a map at the REPL, it will put `,’s between each key/value pair. These are purely used for readability - commas are treated as whitespace in Clojure. Feel free to use them in cases where they help you!
What does % m mean in Clojure?
The (% m) may look a little weird, it's idiomatic Clojure for applying a key to a map to look up the associated value. Most highly recommended reading: The Clojure Cheat Sheet . I thought about going trough sequences as you've done in your example. I also like the name of you're function much more than my own :)
What are Clojure collection types?
As described in the previous section, there are four key Clojure collection types: vectors, lists, sets, and maps. Of those four collection types, sets and maps are hashed collections, designed for efficient lookup of elements. Sets are like mathematical sets - unordered and with no duplicates.

When to Use A Hashmap?

A hashmap is useful when you want to give names to your variables. If you’re ever thinking to yourself, “What if I used an object…”before you snap out of it and realize you’re using Clojure, try using a hashmap. They are also useful if you want to associate two different values with each other. Take, for example, a ROT13 cipher – you could associat

Keywords and Retrieving Values from Hashmaps

Hold up. What is this? :a? :b? :c? Those look odd. Those, you see, are keywords. They’re called key-words because they’re often used as keys in hashmaps. Why are they often used as keys? Well, unlike strings, keywords can be used as functions to extract values from a hashmap; no need for get or nth freecodecamp.org

Update A Hashmap

You can update values inside a hashmap using assoc. This allows you to append new key/value pairs or change old ones. freecodecamp.org

Converting Other Collections to Hashmaps

Converting to a hashmap is tricky. To demonstrate, let’s try using it like vec or seq. The hash-map function thinks that we’re trying to create a hashmap with [:a 1 :b 2 :c 3]as one of the keys. Watch what happens if we give it the right number of arguments: To convert a sequence to a hashmap, you’ll need to use and understand apply. Luckily, this
