## 【JavaScript】2以上の配列の差分を新たな配列として返す方法(array-diff) How to return the difference between two sequences as a new array.js
const arr = [1, 2, 3, 4, 6]
const arr2 = [1, 2, 3, 4, 5]
const arr3 = [...arr, ...arr2]

for (let [i, e] of arr3.entries()) {
  if(!arr.includes(e)) a.push(e)
  if(!arr2.includes(e)) a.push(e)
}
console.log(a)
