checkEqual([1, 2, 3], [3, 1, 2]) //true

checkEqual([1, 2, 3], [1, 2]) //false (different length)

checkEqual(['a', 'b', 'c'], ['a', 'b', 'c']) //true

//Check two Objects

checkEqual(
  { a: '1', b: 2, c: false, d: [1, 3, 5, 7], e: { x: 'x', y: 'y' } },

) //true

checkEqual(
  { a: '1', b: 2, c: false, d: [3, 7, 1, 5] },

  { a: '1', b: 2, c: false, d: [1, 3, 5, 7] }

checkEqual(
  { a: '1', b: 2, c: false, d: [1, 3, 5, 7], e: { x: 'x', y: 'y', z: 'z' } },

  { a: '1', b: 2, c: false, d: [1, 3, 5, 7], e: { x: 'x', y: 'y' } }
) //false

checkEqual({ a: '2', b: 2, c: false }, { a: '1', b: 2, c: false }) //false

checkEqual({ a: '1', b: 2, c: true }, { a: '1', b: 2, c: false }) //false
