누군가 React로 나를 도울 수 있습니까?

import React from "react";
import "./styles.css";

try {
  console.log(test); // undefined
  const test = "THIS IS FOR TEST";
} catch (error) {
  // I don't understand why it doesn't throw the reference error.. 😫
  console.log(error);
}

export default function App() {
  return (
    <div className="App">
      <h1>Hello CodeSandbox</h1>
      <h2>Start editing to see some magic happen!</h2>
    </div>
  );
}

try {
  console.log(test);
  const test = "THIS IS FOR TEST";
} catch (error) {
  console.log(error);
  // ReferenceError: Cannot access 'test' before initialization
    at <anonymous>:2:15
}
