Gotta try to access var from outside a function block (I know you can access from within a function in different blocks) .... Nice video leaving viewers some homework and not explaining everything which is actually not a bad thing cause then it's less likely that people like me would try anything .... Good job 👍

Thanks for a short and concise explanation! Which environment do you use to run the js you just typed? It looks a bit like sublimetext to me, but where does the console come from - is that built in to the text editor? I'd like to try that too, looks very handy!

Const variables are not immutable. Only their references or bindings are, don’t throw around the term immutability in a language like JavaScript
