[removed] Passing parameters to a callback function

Question

I\'m trying to pass some parameter to a function used as callback, how can I do that?

function tryMe (param1, param2) {
    alert (param1 + \" and \" + param         


        

Answer 1

function tryMe(param1, param2) {
  console.log(param1 + " and " + param2);
}

function tryMe2(param1) {
  console.log(param1);
}

function callbackTester(callback, ...params) {
  callback(...params);
}



callbackTester(tryMe, "hello", "goodbye");

callbackTester(tryMe2, "hello");
