The mappath function

Continuing to enhance our micro functional library, here is the mappath function.

mappath (propertypath, arrayofobjects) => arrayofpropertyvalues

Example :

let pets = [ { petname : "Bill", breed : "poodle", weight: 12, owner : { ownername : "Paul", contribution : { amount : 32, payed : false }, address : { city : "Paris" } } }, { petname : "Maya", race : "pointer", weight: 27, owner : { ownername : "Henri", contribution : { amount : 12, payed : true }, address : { city : "London" } } }, { petname : "Ooper", race : "setter", weight: 20, owner : { ownername : "Nicolas", contribution : { amount : 12, payed : true }, address : { city : "London" } } } ]
Enter fullscreen mode Exit fullscreen mode

Let's retrieve all the amount values;

 const amountpath = "owner.contribution.amount" console.log(mappath(amountpath, pets))
Enter fullscreen mode Exit fullscreen mode

For me, that is more readable and testable, but that is a matter of taste.

Result :
