pub struct Reflect { /* fields omitted */ }
The static Reflect.apply()
method calls a target function with
arguments as specified.
MDN documentation
The static Reflect.construct()
method acts like the new operator, but
as a function. It is equivalent to calling new target(...args)
. It
gives also the added option to specify a different prototype.

MDN documentation
The static Reflect.defineProperty()
method is like
Object.defineProperty()
but returns a Boolean
.
MDN documentation
The static Reflect.deleteProperty()
method allows to delete
properties. It is like the delete
operator as a function.
MDN documentation
The static Reflect.get()
method works like getting a property from
an object (target[propertyKey]
) as a function.
MDN documentation
The static Reflect.getOwnPropertyDescriptor()
method is similar to
Object.getOwnPropertyDescriptor()
. It returns a property descriptor
of the given property if it exists on the object, undefined
otherwise.
MDN documentation
The static Reflect.getPrototypeOf()
method is almost the same
method as Object.getPrototypeOf()
. It returns the prototype
(i.e. the value of the internal [[Prototype]]
property) of
the specified object.
MDN documentation
The static Reflect.has()
method works like the in operator as a
function.
MDN documentation
The static Reflect.isExtensible()
method determines if an object is
extensible (whether it can have new properties added to it). It is
similar to Object.isExtensible()
, but with some differences.
MDN documentation
The static Reflect.ownKeys()
method returns an array of the
target object's own property keys.
MDN documentation
The static Reflect.preventExtensions()
method prevents new
properties from ever being added to an object (i.e. prevents
future extensions to the object). It is similar to
Object.preventExtensions()
, but with some differences.
MDN documentation
The static Reflect.set()
method works like setting a
property on an object.
MDN documentation
The static Reflect.set()
method works like setting a
property on an object.
MDN documentation
The static Reflect.setPrototypeOf()
method is the same
method as Object.setPrototypeOf()
. It sets the prototype
(i.e., the internal [[Prototype]]
property) of a specified
object to another object or to null.
MDN documentation
The hasOwnProperty()
method returns a boolean indicating whether the
object has the specified property as its own property (as opposed to
inheriting it).
MDN documentation
The isPrototypeOf()
method checks if an object exists in another
object's prototype chain.
MDN documentation
The propertyIsEnumerable()
method returns a Boolean indicating
whether the specified property is enumerable.
MDN documentation
The toLocaleString()
method returns a string representing the object.
This method is meant to be overridden by derived objects for
locale-specific purposes.
MDN documentation
The valueOf()
method returns the primitive value of the
specified object.
