I’m just confused, does it nescessary to declair void return type in our code ? Because whe use ‘void’ when the function does not return any value, and if function does not return any value, why we must write a type annotation for it ? Sorry for my stupid question, I’m just don’t know the uses of this return type.


Upon research, it’s to help with readability. If you’re reading some code and want to quickly know whether a function returned anything, using void in the type annotation can be helpful and let you know that nothing is returned.

But apparently, void doesn’t actually mean the function returns nothing. Instead, it means “I don’t care about the return value”

I’m confused now because that seems to be against what this lesson taught and now I have no idea how to use void.
