How to print a string that is inside an object in js?

Question

I have an object named promise and it has functions and string inside it. For printing the object i can use

console.log(promise);

but i have a string named "responseText" inside promise. If i try to print it using

console.log(promise.responseText);

,its showing as undefined. I can see the value of responseText by printing the object. But when i print using promise.responseText its showing undefined.

FYI

I am able to print all the functions inside promise, but I am not able to print the string. Please help.

I am printing it as console.log(obj.responseText); only. Editted the post. — Mohamed Alsad

I suspect your promise is doing some async operation and is not completed at the time you did console.log. The classic async problem. — abhishekkannojia

Use

var promise = {
  responseText: function(){
    return "responseText"
  }
}

console.log(promise.responseText())

OR

var promise = {
  responseText: function(){
    console.log("responseText")
  }
}

promise.responseText()
