Can Someone help with this challenge?

Confused about the addition part in this question

let ages = [12,10,11,42,35,27,91,82,26,33,37,15]

let total = ages.reduce {}

What's the issue? Are you having an error? Try ages.reduce() instead.

Yer it should work if you use ages.reduce() instead of ages.reduce{}

Let me know if it still doesn't work!
