在for循环中进行解构时，尝试在null对象上调用

const arr = [1, 2, 3];
const [a, b, c] = arr;
console.log(a, b, c); // 输出: 1 2 3

const obj = { x: 1, y: 2, z: 3 };
const { x, y, z } = obj;
console.log(x, y, z); // 输出: 1 2 3

const nullObj = null;
const [a, b, c] = nullObj; // TypeError: Cannot destructure property '0' of 'null' as it is null.

const nullObj = null;
if (nullObj !== null) {
  const [a, b, c] = nullObj;
  console.log(a, b, c);
} else {
  console.log("nullObj is null");
}
