Tell us what’s happening:

When isn’t right please tell me?

Your code so far


const sum =(...args) => {
return args.length > 0 ? args.reduce((num, i) => num+=i) : 0
}
console.log(sum(2,3,4));

Looks like you overcomplicated the solution.

Don’t use the rest operator at the beginning of the function , but use it when the 2nd function inside the wrapper function is returned. So modify below “use strict”. You may have to reset your code to do it easily.

Yeah, but is good to know it is not your fault.

I think you have a colon not a comma right before your initial accumulator. The 0

Also look at your parentheses grouping
