Suggested Changes

I'm reading through the documentation in https://typescript-eslint.io/rules/no-unnecessary-boolean-literal-compare/#fixer and seeing the following part:

I believe both of them are wrong, i.e. the statement in comparison and fixer output are not equal.

To show how those are wrong, we can simply compare final evaluation result for each possible value of nullableBooleanVar = true, false, and undefined. (null will be treated as same as undefined).

As shown above, we can see that the reported Fixer Output on the right-side will use expression that evaluate to different value from the original code on the middle.

Again, as shown above, we can see that the reported Fixer Output on the right-side will use expression that evaluate to different value from the original code on the middle.

I can't advise about what the correct (expected) Fixer Output should be. The reason why I read this documentation in the first place is because I'm not sure how to fix my code. Yet the documentation gives incorrect information.

Also, I'm not sure whether this issue is also happen to your Fixer utility, since I'm not using it. I always fix lint error by hand ;-) or IDE.

Thanks.
