I would appreciate it if you could verify this for me: Apart from carrying out their specific functions, is the primary advantage of .map() and .filter() that they offer a level of abstraction? It seems like abstraction in action when they create new arrays containing selected data elements without altering the original array.
The concept of the map function can be traced back to its roots in functional programming principles (https://en.wikipedia.org/wiki/Functional_programming). In the realm of this programming paradigm, the use of "pure functions" is emphasized, which are functions that do not alter any of their arguments.
Therefore, it's more of a deliberate decision than just an abstraction:
In certain scenarios, preserving the integrity of the original data is crucial, making map a suitable choice by default.
Alternatively, there may be situations where you have the freedom to choose. Utilizing map offers the benefit of minimizing potential side-effects (e.g., other parts of the application sharing the same array and not anticipating alterations), albeit at the expense of duplicating data.
Hence, neither option is inherently superior; it ultimately hinges on the specific objectives you aim to achieve.
