anything in js
the hash of the object (string(32))
const a1 = [1, 2, 3, 4];
const a2 = [1, 2, 3, 4];
expect(toHashCode(a1)).toBe(toHashCode(a2));
const o1 = { a: 1 };
const o2 = { a: 1 };
const o3 = { a: 2 };
expect(toHashCode(o1)).toBe(toHashCode(o2));
expect(toHashCode(o1)).not.toBe(toHashCode(o3));
expect(toHashCode('simple')).toBe(toHashCode('simple'));
expect(toHashCode('11')).not.toBe(toHashCode(11));
Object.toHashCode
remember: the SAME structure object will return the SAME hash code
