Type Definitions

JSChar	A UTF-16 code unit.
JSClassAttributes	A set of `JSClassAttribute`s.
JSClassRef	A JavaScript class. Used with `JSObjectMake` to construct objects with custom behavior.
JSContextGroupRef	A group that associates JavaScript contexts with one another. Contexts in the same group may share and exchange JavaScript objects.
JSContextRef	A JavaScript execution context. Holds the global object and other execution state.
JSGlobalContextRef	A global JavaScript execution context. A `JSGlobalContext` is a `JSContext`.
JSObjectCallAsConstructorCallback	The callback invoked when an object is used as a constructor in a `new` expression.
JSObjectCallAsFunctionCallback	The callback invoked when an object is called as a function.
JSObjectConvertToTypeCallback	The callback invoked when converting an object to a particular JavaScript type.
JSObjectDeletePropertyCallback	The callback invoked when deleting a property.
JSObjectFinalizeCallback	The callback invoked when an object is finalized (prepared for garbage collection). An object may be finalized on any thread.
JSObjectGetPropertyCallback	The callback invoked when getting a property's value.
JSObjectGetPropertyNamesCallback	The callback invoked when collecting the names of an object's properties.
JSObjectHasInstanceCallback	The callback invoked when an object is used as the target of an `instanceof` expression.
JSObjectHasPropertyCallback	The callback invoked when determining whether an object has a property.
JSObjectInitializeCallback	The callback invoked when an object is first created.
JSObjectRef	A JavaScript object. A `JSObjectRef` is a `JSValueRef`.
JSObjectSetPropertyCallback	The callback invoked when setting a property's value.
JSPropertyAttributes	A set of `JSPropertyAttribute`s.
JSPropertyNameAccumulatorRef	An ordered set used to collect the names of a JavaScript object's properties.
JSPropertyNameArrayRef	An array of JavaScript property names.
JSStringRef	A UTF16 character buffer. The fundamental string representation in JavaScript.
JSTypedArrayBytesDeallocator	A function used to deallocate bytes passed to a Typed Array constructor. The function should take two arguments. The first is a pointer to the bytes that were originally passed to the Typed Array constructor. The second is a pointer to additional information desired at the time the bytes are to be freed.
JSValueRef	A JavaScript value. The base type for all JavaScript values, and polymorphic functions on them.
