Benchmark: Object cloning with Lodash cloneDeep vs ES6 object spread vs JSON.stringify

HTML Preparation code:

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

Script Preparation code:

var o = {
 a: {
   b: 1,
   c: 2,
   d: 3,
   j: {
     k: [1,2,3],
     l: [4,5,6]
   },
 },
 e: [1,2,3,4,5,6],
 f: 1,
 g: {
   h: 1,
 }
}

Tests:

Lodash cloneDeep
const a = _.cloneDeep(o)
ES6 spread
const a = { ...o, a: { ...o.a, j: { ...o.a.j, k: [...o.a.j.k] } } };
JSON.stringify
const a = JSON.parse(JSON.stringify(o));
