Answer 1

No, this would be like accessing any other variable prior to initialization. Here, 'sum' is a variable that holds an alias for the anonymous arrow function, so it is treated similarly to any other variable and not like a normal function etc.

Answer 2

If you are using an arrow function inline or passing as an argument to another function without an alias, then the arrow function needs to be fully defined. If you are using an alias variable for an arrow function then, yes, that alias must be initialized with a fully defined arrow function prior to being called.

Answer 3

ChaoticDawg are arrow functions meant to be initialized before call?
