Lesson 1: Welcome to Remix! Simple Storage

[vk00007]

In the FCC blockchain tutorial, why can't we have uint256 returning in the function retrieve, why is it separately returns(uint256). Is returns another function here? if so why is retrieve() used here at all.

PS: An absolute beginner here, forgive me if this is very basic

Hello @vk00007
In solidity the returns statement is just to specify the type of data you are going to return, the reason we create this function is because you will not always use REMIX, as favoriteNumber is a public variable, Remix automatically set up a button for you, but when you are going to develop locally you will not have it, so the retrieve function is a getter function.

Hello @Odinaka12

Please use code editor to pass your code next time instead of photo of screen. Your curly brackets "{ }" are posted incorrectly. You have closed your contract coding just in line 8, and you should closed it after all functions and variables.

Thank you, I get it now.

Hi,

Appreciate if someone can help me here. I tried to search for JavaScript, but couldn't. What did I do wrongly?

Thanks.

Hello @solidityb
For Javascript? could you be more specific on the question?
If you mean to use the integrated blockchain on remix, using (London or Berlin) should be enough.

Hello @cromewar
I bet he means that Patrick on video has below:

I'm not sure if it is his custom VM or not but I have already replied in separate dicussion posted by @solidityb that using Remix VM (London) will be the same.

Yes, I was following the video, got confused. Thanks :)
