Tell us about your environment

• ESLint Version: 6.1.0
• Node Version: 10.16.0
• npm Version: 6.9.0

What parser (default, Babel-ESLint, etc.) are you using?

default

Please show your full configuration:

module.exports = {
  parserOptions: {
    ecmaVersion: 6,
  },
};

What did you do? Please include the actual source code causing the issue.

There are 4 rules that report ObjectPattern properties, it's probably a bug because there are no examples in the documentation and there are no test cases.

/*eslint quote-props: "error"*/
/*eslint key-spacing: "error"*/
/*eslint no-useless-computed-key: "error"*/
/*eslint computed-property-spacing: "error"*/

({
    a : foo,
    ["b" ]: bar
} = baz)

What did you expect to happen?

No warnings.

What actually happened? Please include the actual, raw output from ESLint.

4 warnings, one for each of the rules.

Are you willing to submit a pull request to fix this bug?

Yes, for whatever is decided.

quote-props and key-spacing are not working well at the moment (see PRs #12046 and #12047), I guess these fixes should be applied to skip ObjectPattern for now. A possible enhancements could be to add options later.

no-useless-computed-key and computed-property-spacing might work well already. Possible actions could be:

• Fix to ignore ObjectPattern.
• Or, consider this as a default behavior feature (it already is) - just modify the docs and add test cases.
• Maybe add options instead.
