@ayormeday That wouldn't work, as it assumes that the item is always at index 2, and replaces 1 item at index 2. Your solution is close though.
function insertIntoMiddle(array, item) {
let middle = array.length / 2;
array.splice(middle, 0, item);
return array;
}
array.splice takes 3 arguments, which are:
the position or index of the item you're replacing
the number of items you're replacing (set to 0 if you want to insert)
the item you're replacing So by this logic, you need to get the index of the item in the middle, (the variable middle), then replace 0 items at index middle with item.
Hope this helps! If it's a bit confusing, feel free to ask questions.
function insertIntoMiddle(array, item) {
}
/ Do not modify code below this line /
Modify the function to insert the given number into the exact middle of the array and return the array.
const items = insertIntoMiddle([1, 3], 2);
console.log(insertIntoMiddle([1, 3], 2), '<-- should be [1, 2, 3]');
console.log(insertIntoMiddle([1, 3, 7, 9], 5), '<-- should be [1, 3, 5, 7, 9]');
Do you have any code yet? We can't just give you answers for your homework, but if you have any questions or errors we can help.

array.splice(2,1,item);
