I’m not sure if I did something wrong but shouldn’t the answer be the 1st one? At the bottom it says tempObj.num is correct.
The description at the bottom is accurate. There is a getter named num
, which does not get called like a traditional method. You can access it like other properties of the object.
If #1 didn’t work to access the value, then #3 would also not work, but they both do.
Consider the following:
const test = {
_message: 'hello, world',
get message() {
return this._message;
},
set message(msg) {
this._message = msg;
},
regularMethod() {
return this.message;
}
};
console.log(test.message); // hello, world
test.message = 'testing';
console.log(test.message); // testing
console.log(test['message']); // testing
console.log(test._message); // testing
console.log(test['_message']); // testing
test['message'] = 'turtles';
console.log(test.message); // turtles
console.log(test.regularMethod()); // turtles
console.log(test.message()); // TypeError: test.message is not a function
Using getters and setters allows you to use standard notation to access the values rather than call object methods directly. Notice that from within the regularMethod()
, we can use the getter of the object as well.
Oh sorry, I’m such an idiot. I somehow read the question too fast and didn’t see the ‘not’. Thank you for responding anyhow.
No, you’re not. You’re learning, and making mistakes is part of that. Positive self-talk is part of a growth mindset, which will really help you along the way.
I also know that you didn’t ask for this interjection from me; I saw that you said this about yourself and I just couldn’t help but step in and share this. How we speak to ourselves can have a big impact on our success, and I want you to be successful
