I watched this video : https://www.youtube.com/watch?v=ae5sqxUmL70 on the topic, which seems to be explained pretty clearly and helped me understand the purpose of getters and setters.
However when I tried to write the same code in the console, it comes back with an error, screenshot below. I’m confused because the code is exactly the same as in the tutorial video - have I missed something?
What was the original code? it is hard to find your reference through video. It is time consuming
Hi @chunzg,
I copied your code to console and it worked. You are getting this error because you have declared this person already.
Hello there,
I only get that error, when I try to redefine person:
Seeing as person is defined as a constant, you cannot re-assign anything to that variable name.
Just as a word of warning: It is quite bad code doing this: ${person.firstName} ${person.lastName}
It should be: ${this.firstName} ${this.lastName}
Hope this helps
Thank you for this tip!
You’re right, thanks. I opened a new incognito window and it worked fine.
Is there a proper way to get rid of a previously declared variable, I thought that by clearing the console with clear() would do the trick?
Hi @chunzg,
Not that I know of, the clear console would not work here as it clears visible history only.
However if your goal is just to play around with it, you can copy your code across every time with different name, like: person1, person2 , person3 etc.
Thanks that makes sense.
