如何从数组动态创建javascript变量？

const arr = ["apple", "banana", "cherry"];

for (let i = 0; i < arr.length; i++) {
  window[arr[i]] = `这是${arr[i]}`;
}

console.log(apple); // 输出：这是apple
console.log(banana); // 输出：这是banana
console.log(cherry); // 输出：这是cherry

const arr = ["apple", "banana", "cherry"];
const dynamicVariables = {};

for (let i = 0; i < arr.length; i++) {
  dynamicVariables[arr[i]] = `这是${arr[i]}`;
}

console.log(dynamicVariables.apple); // 输出：这是apple
console.log(dynamicVariables.banana); // 输出：这是banana
console.log(dynamicVariables.cherry); // 输出：这是cherry
