Tell us what’s happening:

  **Your code so far**


const sum = (x, y, z) => {
const args = [x, y, z];
return args.reduce((a, b) => a + b, 0);
}

Hi @yamashita !

Welcome to the forum!

Reset the lesson.

You only need to change this line here

It should look similar to this example line here

function howMany(...args)

The function should take in any number of arguments and return the sum.
Not just three.

Here is the official documentation that shows more examples of how this works.
