It’s an amazing thought - I’ve considered wishing I had learnt languages in a certain order.
For example, learning a language similar to that of C# where you can clearly differentiate minor differences such as declaration and instatisation of structures and variables, as opposed to say Python.
But then again, from an educational point of view would it be too much of a struggle as a teacher to get a younger age group to understand these wider concepts used in more syntactically advanced languages?
