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)
jQuery Extend
const a = $.extend({}, o);
lodash assign
const a = _.assign({}, o)
JSON Parsing
const a = JSON.parse(JSON.stringify(o));
