如何比较两个字符串数组，不区分大小写，与排序无关- JS，ES6

const array1 = ["Apple", "banana", "Orange"];
const array2 = ["apple", "BANANA", "orange"];

const lowerCaseArray1 = array1.map(item => item.toLowerCase());
const lowerCaseArray2 = array2.map(item => item.toLowerCase());

const string1 = JSON.stringify(lowerCaseArray1);
const string2 = JSON.stringify(lowerCaseArray2);

if (string1 === string2) {
  console.log("两个字符串数组相等");
} else {
  console.log("两个字符串数组不相等");
}
