Not sure if what I want is possible, but
This works:
pointer = arr1 = ['a','b','c'];
arr1.splice(0, 1);
console.log(pointer); // ['b','c']
What I would like, but does not work:
pointer = arr1 = ['a','b','c'];
arr1 = ['e','f'];
console.log(pointer); // desired ['e','f']
console.log(pointer); // reality ['a','b','c']
Is there any way around this, other than constantly re-updating the pointer variable each time arr1 gets reassigned?
No, JavaScript doesn't have pointers. The only way would be if you put the Array in an Object, then updated the Object's Array. Then any reference to the Object would see the update.
var pointer = arr1 = {array:['a','b','c']};
arr1.array = ['e','f'];
console.log(arr2.array); // ['e','f']
console.log(pointer.array); // ['e','f']
Javascript do not have pointers.
Suggestion given by @user2736012 in comments is a good idea ie to put Array in an Object, then updated the Object's Array. Then any reference to the Object would see the update.
