Tell us what’s happening:
Describe your issue in detail here.

this has nothing to do with the challenge. my problem concern the example that was shown on this challenge, that when you u want to do a splice(3,2) , the 3rd and 4th element gets spliced. i can see the third by the fourth doesnt make sense considering the ending index is at 2.
Your code so far


const arr = [2, 4, 5, 1, 7, 5, 2, 1];
// Only change code below this line

// Only change code above this line
console.log(arr);

Challenge: Remove Items Using splice()

The second argument is not a stop index. It is a number of elements to slice out.

oh i see that explains alot. . so that explains why the other example spliced out the element 3 and 4 after (2,2). so confusing because python splicing is way different.

the js slice method works more like you are thinking, the splice method has this different syntax
