1// To compare arrays (or any other object):
2// Simple Array Example:
3const array1 = ['potato', 'banana', 'soup']
4const array2 = ['potato', 'orange', 'soup']
5
6array1 === array2;
7// Returns false due to referential equality
8JSON.stringify(array1) === JSON.stringify(array2);
9// Returns true

12// Another Example:
13const deepArray1 = [{test: 'dummy'}, [['woo', 'ya'], 'weird']]
14const deepArray2 = [{test: 'dummy'}, [['woo', 'ya'], 'weird']]
15
16deepArray1 === deepArray2;
17// Returns false due to referential equality
18JSON.stringify(deepArray1) === JSON.stringify(deepArray2);
