你可以使用Array#filter来获取第一个数组中不在第二个数组中的所有元素。
let array1 = ['2023-04-05','2023-04-06','2023-04-07'];
let array2 = ['2023-04-07'];
let res = array1.filter(x => !array2.includes(x));
console.log(res);
英文:
You can use Array#filter to get all elements in the first array not present in the second.

let array1 = ['2023-04-05','2023-04-06','2023-04-07'];
let array2 = ['2023-04-07'];
let res = array1.filter(x => !array2.includes(x));
console.log(res);
