Tests:
stringify md5
testObj2.age = Math.random(); testObj2.index = Math.random(); const testObjHash1 = objectHash(JSON.stringify(testObj1), {algorithm: 'md5'}); const testObjHash2 = objectHash(JSON.stringify(testObj2), {algorithm: 'md5'}); testObj1 === testObj2;
#hashes
testObj2.age = Math.random(); testObj2.index = Math.random(); const testObjHash1 = objectHash(testObj1, {algorithm: 'md5'}); const testObjHash2 = objectHash(testObj2, {algorithm: 'md5'}); testObj1 === testObj2;
isEqual (objects)
testObj2.age = Math.random(); testObj2.index = Math.random(); _.isEqual(testObj1, testObj2);

Measuring performance of JavaScript functions and libraries is an essential part of software development. I'll break down the benchmark and its results, explaining what's being tested and the pros and cons of each approach. **Benchmark Overview** The benchmark consists of three individual test cases: 1. `stringify md5`: Compares two objects (`testObj1` and `testObj2`) after modifying their properties using `Math.random()`. 2. `#hashes`: Compares two objects (`testObj1` and `testObj2`) without modifying their properties. 3. `isEqual (objects)`: Compares the equality of two objects (`testObj1` and `testObj2`) directly. **Test 1: `stringify md5`** This test case compares the modified objects after stringifying them using `JSON.stringify()` and then hashing them with `objectHash` library (version 3.0.0) using the MD5 algorithm. * The purpose of this test is to evaluate the performance of the `objectHash` library when dealing with modified objects. * **Pros:** * This test case helps identify performance issues related to hashing and comparing objects after modifications. * **Cons:** * It may not accurately represent real-world scenarios where objects are rarely modified. **Test 2: `#hashes`** This test case compares the two original objects (`testObj1` and `testObj2`) without modifying their properties. It uses the same `objectHash` library (version 3.0.0) with the MD5 algorithm to hash both objects. * The purpose of this test is to evaluate the performance of the `objectHash` library when dealing with unmodified objects. * **Pros:** * This test case helps identify performance issues related to hashing and comparing original objects. * **Cons:** * It may not accurately represent real-world scenarios where objects are modified. **Test 3: `isEqual (objects)`** This test case compares the equality of the two objects (`testObj1` and `testObj2`) directly using the `_.isEqual()` function from Lodash library (version 4.17.21). * The purpose of this test is to evaluate the performance of the `_.isEqual()` function when comparing equal or unequal objects. * **Pros:** * This test case helps identify performance issues related to comparing objects directly. * **Cons:** * It may not accurately represent real-world scenarios where object equality checks are used with modifications. **Benchmark Results** The benchmark results show the execution time per second for each test case: * `stringify md5`: 762.082 executions per second (Chrome 120, Desktop, Linux) * `#hashes`: 9864.78515625 executions per second (Chrome 120, Desktop, Linux) * `isEqual (objects)`: 2446.115234375 executions per second (Chrome 120, Desktop, Linux) **Conclusion** The results indicate that: * The performance of the `objectHash` library is optimal when dealing with modified objects (`stringify md5`). * The performance of the `objectHash` library is slower than expected when dealing with unmodified objects (`#hashes`). * The performance of the Lodash `_isEqual()` function is good for comparing equal or unequal objects directly. Keep in mind that benchmark results may vary depending on the specific hardware, software configurations, and test environments used.
