Splice() Method - Confusing

[P.Mat3]

I have hit a strange wall. The splice() method is behaving differently from what was explained.

Please take a moment to read the code below.
Console.log(newArray) is only returning one value and I cannot figure out why.
Console.log(newArray2) is returning two values, the first value is the correct ZBI(zero base index), however the second value is not.

May you please explain why, (newArray) is returning only a single value and why (newArray2) is also splicing at the wrong ZBI?

let array = ['I', 'am', 'feeling', 'really', 'happy'];
let array2 = ['Merry', 'Xmas', 'Everyone', 'And', 'Happy--']

let newArray = array.splice(3, 1);
let newArray2 = array2.splice(3, 2);

console.log(newArray);
console.log(newArray2);

Hi @P.Mat3 !

@P.Mat3

Console.log(newArray) is only returning one value and I cannot figure out why.

If you look at the docs it says this:
The return value is an array containing the deleted elements.

Your code here

@P.Mat3

let newArray = array.splice(3, 1);

is telling the computer to remove one element at index 3.

@P.Mat3

Console.log(newArray2) is returning two values, the first value is the correct ZBI(zero base index), however the second value is not.

It is returning two values because that is what the second argument in splice is doing.
Your code here

@P.Mat3

let newArray2 = array2.splice(3, 2);

tells the computer to remove two elements from the array starting at index 3.

Array.prototype.splice() - JavaScript | MDN

Hopefully that clears it up.

Thank you for clarifying.
