TS实现深拷贝、深度克隆

export function clone<T>(value: T): T {
  /** 空 */
  if (!value) return value;
  /** 数组 */
  if (Array.isArray(value)) return value.map((item) => clone(item)) as unknown as T;
  /** 日期 */
  if (value instanceof Date) return new Date(value) as unknown as T;
  /** 普通对象 */
  if (typeof value === 'object') {
    return Object.fromEntries(
      Object.entries(value).map(([k, v]: [string, any]) => {
        return [k, clone(v)];
      })
    ) as unknown as T;
  }
  /** 基本类型 */
  return value;
}
