This is tutorial is amazing, thank you.

[@cryptojesperk]

Thank you very much! 🙏 thanks for watching

[@0xsabir]

This lecture is superb as expected. One suggestion, Please add Mapping in the video title for easier access. As this video is all about Mapping. Something like- "Solidtity Storage: What you need to know about Mapping" ? or "Understanding Mapping in Solidity" ?

[@cryptojesperk]

Excellent idea! Thanks for the suggestion. Thanks for watching! 🙏

[@vipinng2943]

[@PushpendraSingh-ko7ey]

found gem channel...considering me lucky

[@cryptojesperk]

Really appreciate the kind words 🙏

[@noname13345]

Beautiful. Probably off-topic, but Im stuck on debugging .sol files line by line like anyother file (.js, .py etc) since Im having a hard time to just visualize what ever is written in the smart contract and have blind faith in it lol. Any suggestions? Tried hardhat console but didnt work.

[@cryptojesperk]

Thank you very much! 🙏 Try out Foundry and also, depending on the project size, remix can do it too!

[@ujjwalshrestha5720]

great content ✌✌ can you make video on memory and calldata such like this

[@cryptojesperk]

Thanks for watching! Yes, I can definitely do that.

[@playco857]

I know that when we delete data from mapping, it just sets value to zero. In this case, does it mean that hash is also set to zero?

[@cryptojesperk]

Thanks for watching and for your question! No the hash is not set to zero, you can always has the storage slot index and key value to get where that value would have been sitting. The hash is an “on the fly” computation and not “stored anywhere” to be zeroed out- if that makes sense?

[@_izzee7907]

Abi encode and abi encodepacked both of them are giving the storage slot , then in the context of storage both works same???

[@codeWithBala]

whether hash(key , slot) and hash(slot , key ) are same ?

[@cryptojesperk]

Thanks for watching! Great question! No they’re not the same because the underlying bit patterns would generally be different! For example: is different than

[@RitikAgarwalll]

Can You please share the white board content link

[@cryptojesperk]

I don't have the board content, but I am using miro.com/ to create it. I actually end up overwriting these. But I can start adding them to the Github repo as well! Great idea; and thanks for watching!
