What is Angular 8?
Angular Oriana is a client-side TypeScript based framework which is used to create dynamic web applications. It is very similar to its previous versions except having some extensive features.
Note: Dynamic web applications are simply dynamic websites i.e. www.gmail.com, www.yahoo.com, etc. which has tendency to change data/information with respect to 3 parameters:
- Time-to-time (eg. news update webs applications)
- Location-to-location (eg. Weather-report web applications)
- User-to-user (eg. Gmail, Facebook type applications)

Web workers class
JavaScript is single threaded, so it is common for more critical tasks like data calls to take place asynchronously. Web Workers facilitates you to run the CPU intensive computations in the background thread, freeing the main thread to update the user interface.
Web workers can also be helpful, if your application is unresponsive while processing data.
If you want to outsource such a calculation to a background, we must first create the web worker using the Angular CLI.
