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 )

Here are two way to delete node modules.

# The hard way 

- cd into your target folder and according to your OS, run the appropriate command
- linux based systems:  find . -name "node_modules" -type d -prune -exec rm -rf '{}' +
- windows: FOR /d /r . %d in (node_modules) DO @IF EXIST "%d" rm -rf "%d"
