Script Preparation code:

var data = Array(1000000).fill({ a: [{ bar: { c: 3 } }] });

var newGet = (obj, path, defValue) => {
  // If path is not defined or it has false value
  if (!path) return undefined
  // Check if path is string or array. Regex : ensure that we do not have '.' and brackets.
  // Regex explained: https://regexr.com/58j0k
  const pathArray = Array.isArray(path) ? path : path.match(/([^[.\]])+/g)
  // Find value
  const result = pathArray.reduce((prevObj, key) => prevObj && prevObj[key], obj)
  // If found value is undefined return default value; otherwise return the value
  return result === undefined ? defValue : result
}
