Benchmark: Lodash cloneDeep vs structuredClone vs JSON.stringify with array values

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var MyObject = {
    description: 'Creates a deep copy of source, which should be an object or an array.',
    myNumber: 123456789,
    myBoolean: true,
    jayson: {
        stringify: 'JSON.stringify() method converts a JavaScript value to a JSON string....',
        parse: 'JSON.parse() method parses a JSON string...'
    },
    arrayOfValues: [
        'asdf',
        123,
        {
            bob: 's your uncle',
            nestedArray: [123, 333, {
                prop: 123
            }, ]
        },

    ]
};

var myCopy = null;

Tests:

Lodash cloneDeep
myCopy = _.cloneDeep(MyObject);
Native structuredClone
myCopy = structuredClone(MyObject);
JSON.stringify
myCopy = JSON.parse(JSON.stringify(MyObject));
