Reflect

A diferencia de la mayoria de los objetos globales, Reflect no es un constructor. No puede ser instanciado con un operador new o invocando el objecto Reflect como una función. Todas las propiedades y métodos de Reflect son estáticos (igual que los del objeto Math).

El objeto Reflect proporciona las siguientes funciones estáticas con los mismos nombres de los métodos de proxy handler. Algunos de estos métodos son correspondientes a los métodos de Object.

Reflect.apply()

Calls a target function with arguments as specified by the args parameter. See also Function.prototype.apply().

Reflect.construct()

The new operator as a function. Equivalent to calling new target(...args).

Reflect.defineProperty()

Similar to Object.defineProperty(). Returns a Boolean.

Reflect.deleteProperty()

The delete operator as a function. Equivalent to calling delete target[name].

Reflect.get()

A function that returns the value of properties.

Reflect.getOwnPropertyDescriptor()

Similar to Object.getOwnPropertyDescriptor(). Returns a property descriptor of the given property if it exists on the object, undefined otherwise.

Reflect.getPrototypeOf()

Same as Object.getPrototypeOf().

Reflect.has()

The in operator as function. Returns a boolean indicating whether an own or inherited property exists.

Reflect.isExtensible()

Same as Object.isExtensible().

Reflect.ownKeys()

Returns an array of the target object's own (not inherited) property keys.

Reflect.preventExtensions()

Similar to Object.preventExtensions(). Returns a Boolean.

Reflect.set()

A function that assigns values to properties. Returns a Boolean that is true if the update was successful.

Reflect.setPrototypeOf()

A function that sets the prototype of an object.

• The Proxy global object.
• The handler object.
