Coding error ??

[</DeGenerate>]

I was taught const = consistent / doesn't change over time! And let = creates values that are likely to change overtime.


pls see image: and please explain to me why I originally got this question wrong!
I used let for age instead of the apparent correct answer which was const, and this goes against everything this app originally taught me ?!?!?!

Thanks in advance.

We're need for a more details - question text, task context. And this forum specified for Java, not JavaScript.

Once Mino is done with that question it moves onto a different question so their really isn't much context to give. but can yon give me a scenario whereby you would use const for an age value, so I have a better understanding.

thanks for your reply

const can't be used for age value storing. const represents permanent value like Pi, exception messages, RegEx patterns - use it for data that has rarely changes

So why does Mimo tell me I'm wrong when I used the let variable for an age value? I think I may need to flag that on Mimos site.

but thanks for clarifying that I was right

If you are going to change it, while the program is running, use a variable.

If you are not going to change it, while the program is running, use a variable or a constant.

If it must not be changed, while the program is running, and you want to see an error message if the program does change it, use a constant.

Personally, I use variables for everything. That's just my style.
