Which is not a correct way to empty an array?

Question

A. arr = [];
B. arr.length = 0;
C. arr.splice(0, arr.length);
D. While(arr.length > 0) { arr.push();}

Answer 1

Like Kaminorsabir Kamin said, it is an infinite loop.
You are adding elements to the array. So the array length always will be > 0.

Answer 2
