`await` allows the event loop/job queue to run while waiting. However, while using `import` declarations, your module will not run until all imports have completed; this means that your module will be suspended while the dependency awaits.

If your app is shipped as a single bundle this means your entry point would be unable to run anything while dependencies are awaiting if you use `import` declarations. If your app places runtime dependent imports into a dynamic import like using `import()` as a function, it would not be suspended while waiting.
