hello i have creating a pragam that delete one array from another but. And it works fine i think but if i put 2 same value simultaneously, it remove only one value because of second argument of splice function. How can i check after deleting a element again if there any other number left my code is below.
const arr1 = [1, 2, 2, 3, 5, 2, 3, 7];
const arr2 = [2, 3];
let countArr = [];
for (let i = 0; i < arr2.length; i++) {
for (let j = 0; j <= arr1.length; j++) {
if (arr1[j] === arr2[i]) {
arr1.splice(j, 1);
}
}
}
console.log(arr1);<!DOCTYPE html>

</html>here it's pretty forward you can use 2 nested if conditions to check it again if the array still has that value
const arr1 = [1,2,2,3,5,2,3,7];
const arr2 = [2, 3];
for (let i = 0; i < arr2.length;i++){
for (let j = 0; j < arr1.length; j++){
if (arr1[j] === arr2[i]) {
arr1.splice(j, 1)
if (arr1[j] === arr2[i]) {
arr1.splice(j, 1)
}
}
}
}or you can use set to remove any duplicatie values for the array before you begin looping it here you can read more about sets on MDN Documentation
