        arguments: any;
        caller: Function;
        length: number;
        name: string;
        prototype: any;
        "[hasInstance]"(value: any): boolean;
        "[hasInstance]"(value: any): boolean;
        apply(this: Function, thisArg: any, argArray?: any): any;
        apply(this: Function, thisArg: any, argArray?: any): any;
        bind(this: Function, thisArg: any, ...argArray: any[]): any;
        bind(this: Function, thisArg: any, ...argArray: any[]): any;

    arguments: any

    传递给函数的参数。

    The arguments passed to a function. @non-standard

    caller: Function

    调用当前函数的函数。

    The function that invoked the current function. @non-standard

    length: number

    函数期望的参数个数。

    The number of arguments expected by the function.

    name: string

    Returns the name of the function. Function names are read-only and can not be changed.

    prototype: any

    函数的原型。

    The prototype of a function.

    Methods

    • Determines whether the given value inherits from this function if this function was used as a constructor function.

      A constructor function can control which objects are recognized as its instances by 'instanceof' by overriding this method.

      Parameters

      • value: any

      Returns boolean

    • Parameters

      • value: any

      Returns boolean

      如果此函数用作构造函数，则确定给定值是否继承自此函数。

      Determines whether the given value inherits from this function if this function was used as a constructor function.

      构造函数可以通过重写此方法来控制哪些对象被 'instanceof' 识别为其-实例。

      A constructor function can control which objects are recognized as its instances by 'instanceof' by overriding this method.

    • Calls the function, substituting the specified object for the this value of the function, and the specified array for the arguments of the function.

      Parameters

      • this: Function
      • thisArg: any

        The object to be used as the this object.

      • OptionalargArray: any

        A set of arguments to be passed to the function.

      Returns any

    • Parameters

      • this: Function

      要传递给函数的一组参数。

      A set of arguments to be passed to the function.

    • For a given function, creates a bound function that has the same body as the original function. The this object of the bound function is associated with the specified object, and has the specified initial parameters.

      Parameters

      • this: Function
      • thisArg: any

        An object to which the this keyword can refer inside the new function.

      • ...argArray: any[]

        A list of arguments to be passed to the new function.

      Returns any

    • Parameters

      • this: Function
      • thisArg: any
      • ...argArray: any[]

      Returns any
