代码什么意思？是做了深拷贝处理吗

Question

function deepClone(source) {
  if (!source && typeof source !== 'object') {
    throw new Error('error arguments', 'deepClone')
  }
  const targetObj = source.constructor === Array ? [] : {}
  Object.keys(source).forEach(keys => {
    if (source[keys] && typeof source[keys] === 'object') {
      targetObj[keys] = deepClone(source[keys])
    } else {
      targetObj[keys] = source[keys]
    }
  })
  return targetObj
}

deepClone( [ { name: 'alin', age: '18' },  { name: 'baota', age: '45' , child: [ { name: 'bbaota', age: '20'} , { name: 'bbcbo', age: '17'} ] }] )
