Why am I receiving an undefined value when I try to log the createdAnimal?

My main goal with this code is to successfully console.log(createdAnimal) and have the objectAnimal with specific parameters printed out. The following code snippet demonstrates the desired parameters:

animalMaker('cat','flying',true);

Although invoking the animalMaker function works as intended, I am struggling to get the same outcome when using console.log(createdAnimal).

Thank you in advance for any assistance!

Below is the provided code:

function animalMaker(inputType, inputSuperPower, inputCanFly){
  var objectAnimal = {
    'type': inputType,
    'inputSuperPower': inputSuperPower,
    'inputCanFly': inputCanFly,
    'createdBy': 'Scotty'
  };
  console.log(objectAnimal)
}

var createdAnimal = animalMaker('cat','flying',true); 

console.log(createdAnimal);

Answer №1

In order to complete the task, make sure to retrieve the object within the function:

function createAnimal(type, superPower, canFly){
  var animalObject = {
    'type': type,
    'superPower': superPower,
    'canFly': canFly,
    'createdBy': 'Scotty'
  };

  return animalObject;
}

Answer №2

Currently, the animalMaker function does not have a return value. In JavaScript, when a function does not explicitly return a value, it defaults to returning undefined. This means that if you try to assign the result of animalMaker to a variable, it will be set to undefined.

In order for the createdAnimal variable to hold the value of objectAnimal, you need to add a return statement at the end of the animalMaker function:

return objectAnimal;  

It's important to note that any code following a return statement within a function will not be executed, as return marks the end of the function:

function example() {
    return true;
    console.log('This code will never run');
}
