Static variables

staticread onlyprototype:ObjectPrototype

Allows the addition of properties to all objects of type Object.

Static methods

staticassign<T>(target:T, sources:Rest<{}>):T

Copies the values of all enumerable own properties from one or more source objects to a target object.

staticcreate<T>(proto:{}, ?propertiesObject:DynamicAccess<ObjectPropertyDescriptor>):T

Creates a new object with the specified prototype object and properties.

staticdefineProperties<T>(obj:T, props:DynamicAccess<ObjectPropertyDescriptor>):T

Adds the named properties described by the given descriptors to an object.

staticdefineProperty<T>(obj:T, prop:String, descriptor:ObjectPropertyDescriptor):T

staticdefineProperty<T>(obj:T, prop:Symbol, descriptor:ObjectPropertyDescriptor):T

Adds the named property described by a given descriptor to an object.

staticentries(obj:{}):Array<ObjectEntry>

Returns an array containing all of the [key, value] pairs of a given object's own enumerable string properties.

staticfreeze<T>(obj:T):T

Freezes an object: other code can't delete or change any properties.

staticfromEntries<T>(iterable:Any):T

Returns a new object from an iterable of key-value pairs (reverses Object.entries).

staticgetOwnPropertyDescriptor(obj:{}, prop:String):Null<ObjectPropertyDescriptor>

staticgetOwnPropertyDescriptor<T>(target:Array<T>, propertyKey:Int):Null<ObjectPropertyDescriptor>

staticgetOwnPropertyDescriptor(obj:{}, prop:Symbol):Null<ObjectPropertyDescriptor>

Returns a property descriptor for a named property on an object.

staticgetOwnPropertyNames(obj:{}):Array<String>

Returns an array containing the names of all of the given object's own enumerable and non-enumerable properties.

staticgetOwnPropertySymbols(obj:{}):Array<Symbol>

Returns an array of all symbol properties found directly upon a given object.

staticgetPrototypeOf<TProto>(obj:{}):Null<TProto>

Returns the prototype of the specified object.

staticis<T>(value1:T, value2:T):Bool

Compares if two values are the same value. Equates all NaN values (which differs from both Abstract Equality Comparison and Strict Equality Comparison).

staticisExtensible(obj:{}):Bool

Determines if extending of an object is allowed.

staticisFrozen(obj:{}):Bool

Determines if an object was frozen.

staticisSealed(obj:{}):Bool

Determines if an object is sealed.

statickeys(obj:{}):Array<String>

Returns an array containing the names of all of the given object's own enumerable string properties.

staticpreventExtensions<T>(obj:T):T

Prevents any extensions of an object.

staticseal<T>(obj:T):T

Prevents other code from deleting properties of an object.

staticsetPrototypeOf<T>(obj:T, prototype:Null<{}>):T

Sets the prototype (i.e., the internal Prototype property).

staticvalues(obj:{}):Array<Any>

Returns an array containing the values that correspond to all of a given object's own enumerable string properties.
