I want delete duplicate array from two arrays, but just show one of array, how I can do it ? I want result [1, 4]
const arr1 = [1, 2, 3, 4];
const arr2 = [2, 3, 5, 6]
function arrayUniq(arr1, arr2) {
enter code here
}
As @Titus said, just filter the array comparing if one of them have repeated values.
const arr1 = [1, 2, 3, 4];
const arr2 = [2, 3, 5, 6];
function arrayUniq(arr1, arr2) {
const arrays = [...arr1,...arr2]
return arrays.filter(a=> !arr2.includes(a))
}
console.log(arrayUniq(arr1,arr2))// remove duplicates from arr1 and arr2
function arrayUniq(arr1, arr2) {
let result = [];
// Find unique elements in arr1 & push them into result
arr1.forEach((e) => (arr2.find((f) => f === e) ? null : result.push(e)));
// Find unique elements in arr2 & push them into result
arr2.forEach((e) => (arr1.find((f) => f === e) ? null : result.push(e)));
return result;
}
console.log(arrayUniq(arr1, arr2));
