The fastest way to learn it is to have something you want to achieve. We learn better while we need it. You can look at my index, section scripting - Map and list, to learn more :

We usually use map object just like a dictionary. We find a word inside dictionary and get the translation as the result. Usage case such as :
- translate word, "virus" >> a small infectious agent that replicates only inside the living cells of an organism
- Getting price from goods, "tissue" >> $5
- get product name from code, "123000456" >> apple
- getting date from the stored value, "birthday" >> 29 February 2020
- access other map, "attributes" >> return nested map object under this key
I never use map values action anymore nowadays. Because it is easier to use map object inside script. Look at here for simple map related function :
