强制所有内置命令使用 new，String、Number 和 Boolean 除外。

¥Enforce the use of new for all builtins, except String, Number and Boolean.

new Builtin() 和 Builtin() 的工作方式相同，但应优先考虑 new 以与其他构造函数保持一致。强制使用 new 来处理以下内置函数：

¥new Builtin() and Builtin() work the same, but new should be preferred for consistency with other constructors. Enforces the use of new for following builtins:

AggregateError
数组

¥Array
日期

¥Date
错误

¥Error
EvalError
对象

¥Object
Promise
RangeError
ReferenceError
RegExp
SyntaxError
TypeError
URIError

禁止将 new 用于以下内置函数：

¥Disallows the use of new for following builtins:

布尔值

¥Boolean
数字

¥Number
字符串

¥String

这些不应该使用 new，因为这会为原始值创建对象封装器，这不是你想要的。但是，如果没有 new，它们也可以用于将值强制转换为该类型。

¥These should not use new as that would create object wrappers for the primitive values, which is not what you want. However, without new they can be useful for coercing a value to that type.

请注意，需要实例化 new 的内置函数和不需要实例化 new 的内置函数（Symbol 和 BigInt）受 noInvalidBuiltinInstantiation 规则的约束。

¥Note that, builtins that require new to be instantiated and builtins that require no new to be instantiated (Symbol and BigInt) are covered by the noInvalidBuiltinInstantiation rule.
