Benchmark: Lodash.isEqual vs JSON.stringify Equality Comparison for deep nested obj

HTML Preparation code:

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

Script Preparation code:

window.foo = {arr:[{nmr: 1,str: "string" }], obj:{ someField: 'string', nested:{more:[{arrg: 123, str:"string"}]}}};
window.bar = {arr:[{nmr: 1,str: "string" }], obj:{ someField: 'string', nested:{more:[{arrg: 123, str:"string"}]}}}

Tests:

_.isEqual
_.isEqual(window.foo, window.bar)
JSON.stringify
JSON.stringify(window.foo) === JSON.stringify(window.bar);
