О чём код?

The idea is // that if both match, then you can use `util.format`-style args. // Would pass rule: (a, b) => `${b}${a}`. // Would fail rule: (a, b) => `${a}${b}`, and needs to be rewritten. const { expressions } = msg.body; const hasSequentialParams = msg.params.every((param, index) => { const expr = expressions[index]; return expr && expr.type === 'Identifier' && param.name === expr.name; }); if (hasSequentialParams) context.report(msg, errMsg); }, }; }, };
