-@discussion An instance of JSContext represents a JavaScript execution environment. All
- JavaScript execution takes place within a context.
- JSContext is also used to manage the life-cycle of objects within the
- JavaScript virtual machine. Every instance of JSValue is associated with a
- JSContext via a strong reference. The JSValue will keep the JSContext it
- references alive so long as the JSValue remains alive. When all of the JSValues
- that reference a particular JSContext have been deallocated the JSContext
- will be deallocated unless it has been previously retained.
