Codecademy - Truthy or falsy?

/*
It can be hard to keep track of what’s truthy or falsy in JavaScript. Write a function, truthyOrFalsy(), that takes in any value and returns true if that value is truthy and false if that value is falsy.
*/

let truthyOrFalsy = arg => {
  if(arg) {
    return true;
  }
  return false;
}


console.log(truthyOrFalsy(0));
