In #605 I restricted it to binary operations as I didn't know how it would affect boolean operations but it turns out the same technique solves problems that people are reporting. So doesn't make sense to restrict it.
Fixes#824
It turns out that my fix was not correct. We should not add parenthesis for FunctionDeclaration instead of checking if the function expression is named.
Fixes#819
In #596, I fixed a bunch of jsx expression comment edge cases and happened to add a softline there. But it turns out that it's not needed and is actually harmful :)
Fixes#712
Since this is extremely rare, I just took the easy way out and if you are adding a comment inside the "as" node, I just move it outside. We could be more fancy but that works.
Fixes#620
This has come up a couple times on the issue tracker on the react-native-web discussion about Twitter internals. It seems like there's a concensus that people don't break long require calls and they'd rather have it go > 80 columns.

I'm not really sure what a general rule is for those, but starting with LogicalExpressions should be good. Outside of identifiers, function calls and logical expressions, there aren't a lot of things you'd put there in real code anyway.
Fixes#822
Instead of trying to figure out a complicated way to preserve their correct position, it's easier to just migrate those comments before the class.

Printing a merged group indented was actually not the right fix. The right fix was to print them in a single line. It used to have this behavior when I was mutating the first group but now that I don't anymore I need to reproduce this condition.
Fixes#823
We need to add parenthesis around function expressions if they are named otherwise the name leak, but if the function is not named then it's just superfluous.
The conditional change is due to a bad use of switch case where it would fall through the next one. We don't want parenthesis there.
* Add new handleFunctionDeclarationComments function.
* Add dangling comments printing for function params.
* Add new test case.
* Update tests.
* Refactor handleFunctionDeclarationComments to only addDanglingComment when no params.
* Remove unecessary helper function, only attach dangling comments when no params.
* Reset flow tests, no more regression.
It seems like precedence for this combination of operators is very unclear to people (myself included) and consistently adding parenthesis there would be good.
Fixes#773
The idea is that if you reach the end of the `}` inside of a template literal, we have to flush the trailing comma, otherwise it would generate invalid code. We also need the same special case for JSX.
I don't like adding yet another type of document but it seems like the most elegant way to solve the problem.
Fixes#623
* Add handleTemplateLiteralComment helper function.
* Fix handleTemplateLiteralComment function.
* Extend handleTemplateLiteralComment to deal with trailing comments 🚀.
* Add test.
* Make handle comments function naming more consistent, fix merge conflicts.
* Update tests.
* Add better comment injection in Template Literal.
* Pass options to attach function.
* Update tests to match new implementation.
* Fix let -> var in findExpressionIndexForComment for NodeJS v4.
* Reorder after merge conflicts.
* Drop old tests for dangling arrays.
* Replace redundant conditional by a boolean 🚀.
* Refactor implementation.
I originally wanted to expand it but I think that it may not be a good decision because it's very common for them to be empty and you want it to take as little space as possible.
I tried to remove all those conditions but I think that there are valid places where we always want to expand like empty if/for/while loops.
Fixes#778
In addition to Observable, $ or _, we should also add `this` to the list of things that are likely factory and not objects you want to apply things on directly.
I added a way to make the function call break on its own line when it doesn't fit in one line and indent. But I think that only having the indentation is enough, having the call on its own line feels weird.
Fixes#777
