SyntaxError: getter and setter for private name #x should either be both static or non-static
当私有 getter 和 setter 的 static 属性不匹配时，会发生 JavaScript 异常“放置不匹配”。
消息
SyntaxError: Identifier '#x' has already been declared (V8-based) SyntaxError: getter and setter for private name #x should either be both static or non-static (Firefox) SyntaxError: Cannot declare a private non-static getter if there is a static private setter with used name. (Safari)
错误类型
SyntaxError
哪里出错了？
示例
放置不匹配
js
class Test {
static set #foo(_) {}
get #foo() {}
}
// SyntaxError: getter and setter for private name #foo should either be both static or non-static
由于 foo 是 私有的，因此这些方法必须要么都为 static
js
class Test {
static set #foo(_) {}
static get #foo() {}
}
要么都为非静态
js
class Test {
set #foo(_) {}
get #foo() {}
}
