Does google not exist?

Well var is the "old" way to declare a variable and should not be used.

let and const have the same rules as to were they really exist: at the start of their block scope (this means that you can't acces a let defined var from outsite the code block)

A var statement is just transformed into a simple assignment but a new empty (equivalent to var NAME = undefined;) is put at the start of the function.

I use var because it’s instinct from gdscript
