nl_tokens: This function receives a component that has already been associated with an element via a previous call to initialize and updates this element by calling render on the component . When called in normal circumstances it uses the scheduler to defer this update until the next animation frame and will only perform one update of a given component in a given frame . This means you can call update repeatedly in a given tick without causing redundant updates . If this function called during another synchronous update ( for example as a result of a call to update on a child component ) the update is performed synchronously . Returns a promise that will resolve when the requested update has been completed .
