Fall back to raw text if there is a parser error in JS

Handle default value inside object destructuring that way
#163

"Raw text" - does this mean that it won't actually be reformatted? If so, could we instead do something like creating a dummy destructuring to format that we then strip off the unneeded parts of?

[dummdidumm]

Yes, it means it's not formatted at all in the case of { a, b = [] }. It's not great but at least it will unblock formatting the rest of the document.

I did some steps in the "dummy destructuring" direction. It will format such a destructuring if we do let ${expression} = null. But then we have to remove the let and = null from the Doc-Array, which requires some inside knowledge on how the Doc-Structure from the printer looks like. I did not find a quick generic way to cut off the unneeded doc elements.

I'm inclined to merge this. It would unblock devs using the default values at the very minimal cost that only that expression is not reformatted, the rest of the document will be. We can always look into a more sophisticated solution later on. Thoughts?

Yeah, agreed that this partial solution is definitely better than what there is now.
