Is it correct to use non-iterable elements inside a Set?

MDN says that ([])only iterable elements can be used internally .

new Set([iterable]);

However, it's not entirely clear to me. Using this construction, I can put a non-iterable object there, and everything will work. For example: What does MDN mean here?
let set = new Set([{key: 'value'}, 23]);

You need to practice reading the documentation a little.
[] means an optional argument, not an array as you might think.
In your example, you are passing an array, which is an iterable object.
