const myFunction = (param1, param2) => {
  console.log(param1 + param2);
}
myFunction(1, 2);

script.js

const myFunction = (param1, param2) => ({
  result: param1 + param2
});
console.log(myFunction(1, 2));

script.js

const myFunction = (param1, param2) => param1 + param2;
console.log(myFunction(1, 2));

const myFunction = (param1, param2) => {
  let result = param1 + param2;
  return result;
};
console.log(myFunction(1, 2));
