Using Fstring and FText

[unrealsree]

In the lecture “Using using for Type Aliases” the following is done :

using FString = std::string

and replace std:string with FString

FString Guess ="";

Why is the using required ? Why cant we declare a String of type FString class without using “using FString = std::string”

Because we’re not using Unreal yet so we don’t have FString’s
