HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

var foo = {
  name: "Title",
  size: "38041292",
  crc: "a0e2ece5",
  md5: "db0111e93941df77fcb9e911604a7667",
  sha1: "8071353940df7f22a178c401819af4bfd0d3727e"
}

Tests:

Object.Assign
const clonedObject = Object.assign({}, foo);
recursiveDeepCopy
function recursiveDeepCopy(o) { let newO, i; if (typeof o !== 'object') { return o; } if (!o) { return o; } if (Array.isArray(o)) { newO = []; for (i = 0; i < o.length; i += 1) { newO[i] = recursiveDeepCopy(o[i]); } return newO; } newO = {}; for (i in o) { if (o.hasOwnProperty(i)) { newO[i] = recursiveDeepCopy(o[i]); } } return newO; } const clonedObject = recursiveDeepCopy(foo)
