Symbol type in JavaScript

Question

Hello, everyone!

Could you please help me with understanding "symbol" type in JavaScript?

After reading several forums, looking for information in books and web docs, I ended up with the thought that the main reason for introducing this type was to allow JavaScript developers add new features to the language like [Symbol.iterator]() and others without a danger to spoil old code. Please correct me if I'm mistaken.

Also are there any situations when symbols can be handy for ordinary developers?
