Functions§

  • apply
    The static Reflect.apply() method calls a target function with arguments as specified.
  • construct
    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.
  • construct_with_new_target
    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.
  • define_property
    The static Reflect.defineProperty() method is like Object.defineProperty() but returns a Boolean.
  • delete_property
    The static Reflect.deleteProperty() method allows to delete properties. It is like the delete operator as a function.
  • get
    The static Reflect.get() method works like getting a property from an object (target[propertyKey]) as a function.
  • get_f64
    The same as get except the key is an f64, which is slightly faster.
  • get_own_property_descriptor
    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.
  • get_prototype_of
    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.
  • get_u32
    The same as get except the key is a u32, which is slightly faster.
  • has
    The static Reflect.has() method works like the in operator as a function.
  • is_extensible
    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.
  • own_keys
    The static Reflect.ownKeys() method returns an array of the target object’s own property keys.
  • prevent_extensions
    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.
  • set
    The static Reflect.set() method works like setting a property on an object.
  • set_f64
    The same as set except the key is an f64, which is slightly faster.
  • set_prototype_of
    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.
  • set_u32
    The same as set except the key is a u32, which is slightly faster.
  • set_with_receiver
    The static Reflect.set() method works like setting a property on an object.
