Rule suggestion: No spaces in empty array/object declaration

[LinusU]

I would like to propose a rule that prohibits writing empty objects as { } and instead enforces the shorter {} which I think is more commonly used. The same would be true for arrays, it should enforce [] instead of [ ].

Thoughts? If this is wanted I could probably whip up a pull request towards es-lint.

Not particularly fussed on this one, I'm fine with it either way

[LinusU]

I would also be fine with either way, would prefer it if one of them was enforce though, and I have almost only seen without spaces being used in the community...

+1 for {}, I've almost never seen { } without it being a typo.

This sounds good to me. Surprised that this isn't already part of the object-curly-spacing rule.

@LinusU Can you open this as an issue on ESLint to see what the ESLint team thinks? There's nothing we can do in standard until there's a rule in ESLint, so I'm going to close this to keep only actionable issues in the issue tracker.

Once this is part of ESLint, I will notice it in the changelog when I upgrade the ESLint version or you can open an issue/PR to add the rule.

Done: eslint/eslint#7380
