Tangent: why is .match on Symbol? I read through string.match and looked at Symbol and I don’t understand why all these helpful functions exist on Symbol.

Symbol.match is not the match function, it is a Symbol which can be used as a property key on an object that is supposed to behave like a regular expression.

The purpose of having Symbol values is to ensure the property keys are unique and can't collide with string keys that predate new standards.

Also known as "well-known symbols".

Ohhhh okay. So it’s just a flag describing expectations about an object. And as a Symbol it doesn’t interfere with any other part of the object such as properties or iteration.
