[@warodomwerapun6417]

^0.8.20 , some tutorials put this for compatible purpose, not for deploying in the production, then putting ^ symbol is not always wrong, it is depending on the objective of example.

[@heyjonbray]

true, if you're building standalone contracts or working with other compatible versions then specifying an exact compiler version is fine
however some dependencies don't play nice with exact compiler versions, a big one being uniswap periphery contracts and a handful of other very integral dependencies that show up a lot onchain

[@freemindcanada9319]

11:41 for "pure" keyword, I compiled the code example with and without optimization using no mutability, "view" and then "pure", and bytecode is exact same in every case (except for metadata hash ofc)

[@merv893]

Wow that’s a lot of information ,merci

[@EatTheBlocks]

My pleasure!

Congrats!

[@danaherstudio]

Do free functions (or importing scripts) still count towards the size of the contract?
I don't see why they wouldn't but I have my fingers crossed for the opposite lol.

[@bazalkhan9533]

Suggest some courses for beginner to advance in blockchain developement

What about huff ?

Good suggestion. I might do a tutorial on that

Are you trying in Remix?

05:16 😂 Tu as fais ton "et voilà" comme un étranger qui essaie de parler français

[@EatTheBlocks]

Ah non, en Anglais on peut dire voila.

[@jean-michelhiver4362]

So you do a horrible unbounded loop in the iterate() function example, say "et voila", only to let people know in the following trick that doing so is actually a terrible idea. Lol

[@EatTheBlocks]

No, you missed the point. Unbounded loops should be avoided in transactions. If you are just reading data, it's not a transaction.

[@jean-michelhiver4362]

@@EatTheBlocks there is still a gas limit on reads, plus you might well need to use a read function in a write function, so it's still a pretty ugly thing to do imho
