This is an issue when working with changing data hash structures such as responses of APIs. For such a situation, if we were to make validations to check whether the key is available to fetch it would be long, not readable, and would be a not good way of writing code. Using the #dig method we can accomplish that in a concise way and overall it would help to write better code. Using the #dig method it will call itself (#digmeth...
