max-params
在函数定义中强制执行最大数量的参数
带有大量参数的函数可能难以读写，因为它需要记住每个参数是什么、它的类型以及它们应该出现的顺序。因此，许多编码人员遵守了一个约定，该约定限制了函数可以采用的参数数量。
¥Functions that take numerous parameters can be difficult to read and write because it requires the memorization of what each parameter is, its type, and the order they should appear in. As a result, many coders adhere to a convention that caps the number of parameters a function can take.
function foo (bar, baz, qux, qxx) { // four parameters, may be too many
doSomething();
}

doSomething();
