Hi all
Kinda confused as to why using the variable won't work. Can someone help/explain?

let numbers = [2, 3, 4, 5, 6, 7];
let reducer = (...nums) => nums.reduce((prev, next) => prev + next)
let total = reducer(numbers)
//this works
console.log(`Your lucky number is: ${reducer(2, 3, 4, 5, 6, 7)}`)
//this does not
console.log(`The total is ${total}`)

let reducer = (...nums) => nums.reduce((prev, next) => prev + next)
should be
let reducer = (nums) => nums.reduce((prev, next) => prev + next)
then both your examples work.

Array vs. left-variadic sequence.

Just add ... here:
