Suggested Changes

restrict-plus-operands docs starts by giving these incorrect examples:

let foo = '5.5' + 5;

I remember that was once the case, and I don't know when it changed, but now that's not an error anymore. The default configuration is:

const defaultOptions: Options = [
  {
    allowAny: true,
    allowBoolean: true,
    allowNullish: true,
    allowNumberAndString: true,
    allowRegExp: true,
    skipCompoundAssignments: false,
  },
];

Since we have allowNumberAndString: true, it's ok to do '5.5' + 5. It can be verified in the playground.

Also running into this, and it's quite confusing. Shouldn't all of these really default to false instead of true?

The Caution note seems to imply that these shouldn't be set to true at all.

Looks like this issue was fixed by #8362 so can be closed?
