I'm trying to store duplicate arrays into a new array but I keep on getting an empty array in the console. Please help.
function removedIntegers(arr) {
let sortedArr = arr.sort();
let j = [];
for (let i = 0; i < sortedArr.length; i++) {
if (sortedArr[i] != sortedArr[i + 1]) {
j.push(sortedArr[i]);
}
}
return j;
}
Though your code is working fine,
let years = [2020,2020,2021,2021,2022,2023,2024,2025,2026,2027]
function removedIntegers(arr) {
let sortedArr = arr.sort();
let j = [];
for (let i = 0; i < sortedArr.length; i++) {
if (sortedArr[i] != sortedArr[i + 1]) {
j.push(sortedArr[i]);
}
}
return j;
}
console.log(removedIntegers(years))In ES6, the code is simpler than before for duplicate removal.
let years = [2020,2020,2021,2021,2022,2023,2024,2025,2026,2027]
function sortAndUnique(arr){
return [...new Set(arr.sort())]
}
console.log(sortAndUnique(years))
