How different is Solidity 0.8 to 0.5? Your Solidity 0.5 playlist is more complete and has more detailed descriptions, is it still worthwhile to go through the 0.5 playlist? Or would that do more harm than good?

is the 0.5 playlist extremely outdated, because the foundational knowledge and functionality still seems valid?

Q: In the function test, how does 'remove' know you're targeting the 'arr' ? This bit doesn't make sense to me. How does the remove function know you mean to target the arr at index 2, when all you've stated within the remove is a number. That number could mean anything for all the contract knows. Thanks if you could clarify this brother, good videos

I have just started following ur videos and they r really helpful, thanks a lot!!! I am just unable to grasp to the concept of how to view the results of a function.... For example here, how to see the final array after the changes?

thank you very much, God bless you. Just one question: what I need to be a full stack smart contract in addition to solidity?

I wrote the source code above and completed the deployment.
However, remove() and test() did not work normally.

Why?

It's my solidity version 0.8
An error called "VM error: reverse" occurs.

I am studying solidity while watching your video. Thank you so much.
Please understand that I'm not fluent in English. I'm using a translator.

not for usable if you do in real app You pay HIGH gas feee
