Is it possible to disable the typedef rule only for array or object destructuring in lambdas?
getPersonsNames(): string[] {
type Person = { name: string; age: number };
const persons: Person[] = [
{ name: `Jan Kowalski`, age: 12 },
{ name: `Justyna Kowalczyk`, age: 22 }
];
return persons.map(({ name }) => name);
}
I prefer to use typedefs for destructuring, but I want to exclude these specific cases. Is there a way to do this?
I attempted to add 'arrow-parameter': false, (and arrowParameter: false as shown above) to @typescript-eslint/typedef, but it had no effect.
