 * @param {any} obj1 the first object.
 * @param {any} obj2 the second object.
 * @param {boolean} checkDataOrder determine if order  data is relevant on comparison
 *
 * @returns {boolean} return true if obj1 and obj2 have the same data
 *
 * @example
 *
 * expected results:
 * { a: 1, b: 2 } === { a: 1, b: 2 }
 * { a: 1, b: 2 } === { b: 2, a: 1 }
 * { a: 1, b: 3 } !== { b: 2, a: 1 }
 * [1, 2] === [1, 2]
 * [2, 1] === [1, 2]
 * [1, 3] !== [1, 2]
 *
 * but with checkDataOrder = true, the results are different:
 * { a: 1, b: 2 } === { a: 1, b: 2 } // same result as without checkDataOrder
 * { a: 1, b: 2 } !== { b: 2, a: 1 } // different order
 * { a: 1, b: 3 } !== { b: 2, a: 1 } // same result as without checkDataOrder
 * [1, 2] === [1, 2] // same result as without checkDataOrder
 * [2, 1] !== [1, 2] // different order
 * [1, 3] !== [1, 2] // same result as without checkDataOrder
