This rule doesn't exist at the moment. I don't understand what you mean.

I'm coming from eslint and was surprised that it wasn't included. This would be very nice to have!

[jeancatarina]

yes, this is a life changer, its hard for me to leave eslint without this rule

[Conaclos]

The formatter should make you happy?

[unvalley]

This is style related lint rule and eslint will remove (port to stylistic) it, so IMO we should handle this task by formatter in biome.

The formatter is where I would expect this behavior to be found. I came across this discussion because I found some cases where biome format removes empty lines where prettier leaves them as-is or condenses them to one. Here's a playground link demonstrating the difference:

Hi!

Is this being considered?

For me atleast, even though is a simple thing, is also definately a key feature.

Brings so much clearness to the code (withoud manual intervention)
