描述

¥Description

强制使用扩展运算符而不是 .apply()。

¥Enforce the use of the spread operator over .apply().

apply() 方法用于调用一个函数，该函数使用给定的 this 值和以数组形式提供的参数。你可以使用扩展运算符 ... 来实现相同的结果，这种方式更简洁易读。

¥The apply() method is used to call a function with a given this value and arguments provided as an array. The spread operator ... can be used to achieve the same result, which is more concise and easier to read.
