arr1=[1,2,3]
arr2=arr1
what are the possible use cases of the code above, without spread operator? why not simply use arr1 instead of arr2

Yeah I know that, im asking why pass by reference exist, instead of that, simply use the first variable that you referencing
Like, why in order to change arr1 I would want to make another variable
Like,
arr1=[1,2,3]
arr2=arr1
in order to pop 3 from arr1, i can now do arr2.pop(), but why? i can simply do arr1.pop()
