How can i get the three last value in Set Object? Tks alot!

Question

let numbers = [12, 1, 5, 4, 8, 7, 9, 4, 5, 7, 5, 3, , 1, 54, 21, 3, 8, 48,4, , 5, 4, 21, 2, 4, 8, 7, 83, 1, 4, 4, 5, 5, 32, 3, 2, 5, 6, 9, 8, 7, 4, 5, 1, 2, 1, 88, 5, 2, 1, 2, 4, ];

// sort the array
numbers.sort((a,b) => a - b);

// unique value
let numbersNotDup = new Set(numbers);

let [smallNum_1, smallNum_2, smallNum_3] = numbersNotDup;

console.log(smallNum_1);
console.log(smallNum_2);
console.log(smallNum_3);

console.log(numbersNotDup);

Answer 1

if i understand your question, you want to get 1,2 and 4. if this is correct, then you could use the arr.slice function.
numbers.slice(numbers.length-3).

slice can have a begin and end argument. in this case you want to slice at the third to last index of the array. there is no need for the end argument in this case because you want the remaining 3.
