如何删除对象或数组中的递归？

function recursiveDelete(obj) {
  for (var key in obj) {
    if (typeof obj[key] === 'object' || Array.isArray(obj[key])) {
      recursiveDelete(obj[key]);
    } else if (/* 删除条件 */) {
      delete obj[key];
    }
  }
}

var obj = { /* 对象或数组 */ };
recursiveDelete(obj);

def recursive_delete(obj):
  if isinstance(obj, dict):
    for key in list(obj.keys()):
      if isinstance(obj[key], (dict, list)):
        recursive_delete(obj[key])
      elif /* 删除条件 */:
        del obj[key]
  elif isinstance(obj, list):
    for i in range(len(obj) - 1, -1, -1):
      if isinstance(obj[i], (dict, list)):
        recursive_delete(obj[i])
      elif /* 删除条件 */:
        del obj[i]

obj = { /* 对象或数组 */ }
recursive_delete(obj)
