Question 1

Best Practices for variable and function declarations regarding Hoisting

Answer 1

• don’t use var! (use const most of the time and let, if you really need to change the variable later
• declare your variables at the top of each scope
• declare all your functions first and use them only after the declaration (> applies to all types of functions; > you could use function declarations before you declare them but just don’t do that, it’s not clean!)
