How to execute a method passed as parameter to function

Question

I want to write my own function in JavaScript which takes a callback method as a parameter and executes it after the completion, I don\'t know how to invoke a method in my m

Answer 1

I will do something like this

var callbackfunction = function(param1, param2){
console.log(param1 + ' ' + param2)
}

myfunction = function(_function, _params){
_function(_params['firstParam'], _params['secondParam']);
}

Into the main code block, It is possible pass parameters

myfunction(callbackfunction, {firstParam: 'hello', secondParam: 'good bye'});
