  1. You need to declare the variable using const or let

  2. You should include the function body.

const fn = () => {}

what is the difference between let and const in this problem

It wouldn’t be anything specific to this step. You can declare the function both ways.

Personally, I prefer functions to be declared using const as it signals something different from let and I find it quicker to read code that makes that distinction (reassignable vs non-reassignable).

I know a lot of people have started to use let for everything. The main argument is, it is faster to type let.

MDN: declarations
