reference Promise [object Object]
|
Returns a promise which resolves after the element next renders. The promise resolves to `true` if the element rendered and `false` if the element did not render. This is useful when users (e.g. tests) need to react to the rendered state of the element after a change is made. This can also be useful in event handlers if it is desireable to wait to send an event until after rendering. If possible implement the `_didRender` method to directly respond to rendering within the rendering lifecycle. |
