I am learning typescript, and I found this GetParameters type, but it’s not working for me. I am getting the following error:

Parsing error: ';' expected.eslint
Generic type 'GetParameters' requires 1 type argument(s).ts(2314)

what am I doing wrong?

type GetParameters<T extends (...args: any[]) => any> = 
   T extends (...args: infer P) => any ? P : never;


const getPerson = (name: string, age: number) => { 
  return {name, age}
};

function add(a: number, b: number): number {
  return a + b;
}

type PV = GetParameters(getPerson)
