Symbols - Javascript In Depth

We take a look at Symbols in Javascript together. These are a primitive type that are guaranteed to be unique and most commonly used inside of Object properties as keys. We look at some well-known Symbols like Symbol.iterator and how we can use it with Generators to iterate over custom Objects.
