What are Symbols in JavaScript and how can they be used?

Thank you for that question. Symbols, introduced in ECMAScript 2015 or ES6, are a primitive data type unique in JavaScript. They serve as a way to generate a globally unique identifier, but what truly sets them apart is that every symbol value is distinct, regardless of whether they share the same description. This characteristic makes Symbols particularly useful for creating private or protected object properties that cannot be easily accessed or duplicated, enhancing encapsulation and security in our code. To clarify, when you create a Symbol, you can give it a description, which is purely for debugging purposes and has no bearing on the symbol's uniqueness...
