If we were to imagine a scenario where there is an array containing 3 objects, and then I decide to access the second object by its index in order to modify one or more of its properties, what would happen? Would this modification mark the entire array as "dirty"? Would it alter the state of the original array in any way? And does this action result in the variable holding the array being assigned an entirely new array?
All queries receive a negative response, as the array remains untouched and retains objects through references. Unless you assign a new reference to that specific index, the Array remains unaffected. You could even choose to freeze it. The concern lies in possible mutations of the object within the array which may displease certain functional purists.
