Function simpleClone

Remarks

This function uses JSON.parse(JSON.stringify()) which has the following limitations:

• undefined values, functions, and Symbol keys/values are silently dropped
• Date objects are converted to ISO strings (not Date instances)
• RegExp, Map, Set, ArrayBuffer, TypedArray are not properly cloned
• Circular references will throw a TypeError
• NaN and Infinity are converted to null

For full deep cloning support, use deepClone instead.

此函数使用 JSON.parse(JSON.stringify())，存在以下限制：

• undefined 值、函数和 Symbol 键/值会被静默丢弃
• Date 对象会转换为 ISO 字符串（而非 Date 实例）
• RegExp、Map、Set、ArrayBuffer、TypedArray 无法正确克隆
• 循环引用会抛出 TypeError
• NaN 和 Infinity 会被转换为 null

如需完整的深克隆支持，请使用 deepClone。
