如何通过比较JavaScript中的两个arrays的项目来判断是否存在不等项目？

Question

How to find out if there are unequal items by comparing the items of two arrays and return true or false?

let freeDrive = ['58:0', '58:1', '58:22'];
let filterdDrive = ['58:0', '58:1', '58:2', '58:3', '58:4', '58:5', '58:6', '58:7'];

Answer 1

You can do it by iterating on the shorted array and check all its values, the every function is handy for that: https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Global_Objects/Array/every

eg

const checkInclude = (arr1, arr2) => {
  if (arr1.length > arr2.length) {
    return checkInclude (arr2, arr1)
  }
  return arr1.every(v => arr2.includes(v))
}

tested in chrome console

let freeDrive = ['58:0', '58:1', '58:22'];

let filterdDrive = ['58:0', '58:1', '58:2', '58:3', '58:4', '58:5', '58:6', '58:7'];

checkInclude(freeDrive, filterdDrive);

false
