Working with JavaScript Symbols

In this lab, you will practice working with JavaScript Symbols. A JavaScript Symbol is a unique and immutable data type that can be used as an identifier for object properties. Symbols are created using the Symbol() function, and you can also provide an optional description string as an argument. This description is used in the toString() method of the Symbol and serves no other practical purpose.

Create and export multiple symbols from your index.js file using the ESM and learn how to compare them and use Symbol registry.
