setArray(array, newValue: any[]): void
Sets array to a newValue without breaking its memory reference.
It's a much better alternative to doing this:
array = newValue; // this breaks the memory reference.
Examples
arr = [1,2,3,4,5];
arrCopy = arr;
arr = [3,4,5,6,7]; // But does arrCopy get updated too?
console.log(arrCopy);
--> [1,2,3,4,5] // no it doesn't.
// But what if you need arrCopy to stay in-sync with arr?
// Change the value of arr using setArray() instead:
setArray(arr, [3,4,5,6,7]);
console.log(arrCopy);
--> [3,4,5,6,7]; // Success!!
