ESLint Error: prefer-arrow-callback on the reduce method?

Question

I'm getting an the "prefer-arrow-method" eslint error thrown with the reduce function below. I know it's because the function is anonymous but how would I rewrite the reduce method to resolve this error?

   const nameBrand =
     names.brand().reduce(function (sum, name) {
     sum[name] = name;
     return sum;
    }, {});

Answer 1

const nameBrand = names.brand().reduce((sum, name) => {
    sum[name] = name;
    return sum;
}, {});
