11:49 - There are a few other differences between var, let and const.
1. Var can be redeclared while let and const cannot be redeclared.
2. Both var and let can be declared without assigning a value while const needs to have a value assigned when you are declaring it.
3. Additionally during JS execution var is "hoisted" therefore all the var variables are first brought to the start of your code by JS and with an undefined value, before it executes your code. Let and const are not "hoisted" in the sense of the word but are instead stored in temporal dead zone (a memory allocated used to store such variables for the time between declaration and initialization).
