What rule do you want to change?

camelcase

Does this change cause the rule to produce more or fewer warnings?

More warnings.

How will the change be implemented? (New option, new default behavior, etc.)?

New options.

{
    propertiesStyle: "upper" | "lower" | "all",
}

Please provide some example code that this change will affect:

This is bad code example.

const camel = {};
camel.UpperCamelcase = true;

This is good code example.

const camel = {};
camel.lowerCamelcase = true;

What does the rule currently do for this code?

All will be ok. The rule currently do not detect what type of camelcase is using for property.

Unfortunately, it looks like there wasn’t enough interest from the team or community to implement this change. While we wish we’d be able to accommodate everyone’s requests, we do need to prioritize. We’ve found that issues failing to reach accepted status after 21 days tend to never be accepted, and as such, we close those issues. This doesn’t mean the idea isn’t interesting or useful, just that it’s not something the team can commit to.

Thanks for contributing to ESLint and we appreciate your understanding.
