Did you even read it? They don't use the meme 'symbols' but clearly mention 'dynamic property names'.

Dynamic property names are quite different to Symbols in ECMAScript 6.

Use a global const for keygen, 'symbol' is most likely just a syntactic sugar for global const...

[thomasfoster96]

Well a Symbol is guaranteed to be unique (unless you use the symbol registry) and can't be converted to a string - things that you can't say about a global const that is a string.
