clone

_.clone(value)

创建 value 的浅克隆。

¥Creates a shallow clone of value.

注意：此方法大致基于 结构化克隆算法，支持克隆数组、数组缓冲区、布尔值、日期对象、映射、数字、Object 对象、正则表达式、集合、字符串、符号和类型化数组。arguments 对象的自身可枚举属性被克隆为普通对象。对于不可克隆的值（例如错误对象、函数、DOM 节点和 WeakMap），将返回一个空对象。

¥Note: This method is loosely based on the structured clone algorithm and supports cloning arrays, array buffers, booleans, date objects, maps, numbers, Object objects, regexes, sets, strings, symbols, and typed arrays. The own enumerable properties of arguments objects are cloned as plain objects. An empty object is returned for uncloneable values such as error objects, functions, DOM nodes, and WeakMaps.
