Benchmark: Lodash.isEqual vs JSON.stringify Equality Comparison for Object

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.4/lodash.min.js"></script>

Script Preparation code:

window.foo1 = {a: 1, b: {a: 1, b:2, c: [1, 2, 3, [1, 3], {a: 1}]}};
window.foo2 = {a: 1, b: {a: 1, b:2, c: [1, 2, 3, [1, 3], {a: 1}]}, x: ''};
window.foo3 = {a: 0, b: {a: 1, b:2, c: [1, 2, 3, [1, 3], {a: 1}]}};
window.foo4 = {a: 1, b: {a: 1, b:2, c: [2, 3, [1, 3], {a: 1}]}};
window.bar = {a: 1, b: {a: 1, b:2, c: [1, 2, 3, [1, 3], {a: 1}]}};

Tests:
