在一行上重命名导入数组的键(很像解构)

const [firstElement, secondElement] = [1, 2, 3, 4];
console.log(firstElement); // 输出: 1
console.log(secondElement); // 输出: 2

const [renamedFirstElement, renamedSecondElement] = [1, 2, 3, 4];
console.log(renamedFirstElement); // 输出: 1
console.log(renamedSecondElement); // 输出: 2

// 正确的解构赋值
const numbers = [1, 2, 3, 4];
const [num1, num2, ...rest] = numbers;
console.log(num1); // 输出: 1
console.log(num2); // 输出: 2
console.log(rest); // 输出: [3, 4]

// 提供默认值
const [numA = 10, numB = 20] = [];
console.log(numA); // 输出: 10
console.log(numB); // 输出: 20

// 错误的解构赋值
try {
  const [err] = "not an array";
} catch (e) {
  console.error(e); // TypeError: Cannot destructure property '0' of 'not an array' as it is not an object.
}
