Describe your issue in detail here.

Hello, I noticed an error with the result of the example code.
The result of the example code given should be “I am feeling” and not “really happy”.
Thank you
Your code so far

let array = ['I', 'am', 'feeling', 'really', 'happy'];

let newArray = array.splice(3, 2);

console.log(array); // I am feeling, not really happy

The example code is showing the contents of newArray, not the original array.

let array = ['I', 'am', 'feeling', 'really', 'happy'];
let newArray = array.splice(3, 2);
console.log(newArray)

produces

[ 'really', 'happy' ]

splice function works like this:
array.splice(index, how many, item1, …, itemX);

Which means that your index is starting at position 3 in your array.

Good documentation of this function can be found here:
