How can I get the remained part without creating a variable?

[RaymondGuo]

we use Array.splice() to get the part of spliced, I wonder how I can get the remained part, without create another variable and let it = Array.splice().

Your code so far

const arr = [2, 4, 5, 1, 7, 5, 2, 1];
// Only change code below this line
arr.splice(1, 4);
// Only change code above this line
console.log(arr);

splice returns the removed element, so the output of splice is the spliced ones, the mutated array is what is not unspliced

that’s how splice work - if you don’t want to mutate arr you need to use other methods

Yep, what I mean is how I can get the remained part, you have any idea?

[ilenia]

const arr = [1,2,3,4,5,6,7]
const removed = arr.splice(1, 4)
console.log(removed); //array with the removed elements
console.log(arr); // array with remaining elements
