Problem help please

const sum = (...a) => {
  const args = [...a];
  return args.reduce((a, b) => a + b, 0);
console.log(sum(1, 2, 3, 4)); // 6

cant pass the last test

You are not using an args parameter. You have a parameter named a.

The sum function should use the ... rest parameter on the args parameter.

instead your function has an a parameter.

When you use args as a parameter, you should not be declaring it again in your code. I would need to see the code you tried.
