I use the preview get the right output. But system show wrong. I have no clue.

const newText = '$2，$1';

app.js 
function reformatName(text) {
  const rawName = /^(\w+)\s(\w+)$/;

  // Type your answer on line 5, below:
   const newText = '$2，$1'; 

  return text.replace(rawName, newText);
}

const form = document.querySelector("form");
const input = form.querySelector("input");
const reformatted = document.getElementById("reformatted");

form.addEventListener("submit", e => {
  e.preventDefault();
  reformatted.textContent = reformatName(input.value);
});

Yes you are right. Need a space after comma with no reason .
