Issue with "Spread syntax (...)": should it be rest in destructuring?

Hi there,

On the browser compatibility table for the spread syntax, it is mentioned "spread destructuring". Shouldn't it be "rest destructuring" or something along those lines? Initial discussion.

The error when the syntax is with the wrong order also hints at that:

Thanks and have a nice day!

Interesting find. Thanks for reporting this, @arturcarvalho!

I think the problem here is that we've duplicated the data for this syntax:

• incorrectly as javascript.operators.spread.spread_in_destructuring
• correctly (and in more detail) as javascript.operators.destructuring.rest_in_arrays and javascript.operators.destructuring.rest_in_objects (as seen on MDN)

If I've understood correctly, then the fix here would be to delete the spread feature. I'd welcome a PR (from you or another contributor) making this change.

Hi @ddbeck, thanks for the reply!

Exactly, deleting would make the table correct. I can send a PR.
Would it suffice to delete that part you mentioned on the JSON file browser-compat-data/javascript/operators/spread.json?
It looks like a generated file.

Have a nice day.

@arturcarvalho That's correct. Our data files aren't actually generated (though we do a fair amount of automation against them)—think of them as very structured writing. 😃

I laughed out loud with the very structured writing 😄

I'll send a PR after work. Thanks for the reply.
