Workers are just scripts that runs on a separate thread from the main browser thread.  Javascipt has 3 categories:

- Web workers : general purpose workers
- Service workers : proxy between the browser and the network / cache; have custom methods
- Worklets: hook into the browser’s rendering pipeline, enabling you to have low-level access to the browser’s rendering processes such as styling and layout

Workers:
- are registered in the main javascript file of your project
- do not have access to the DOM; thus get messages and props via callbacks ( postMessage & onMessage )
