Tell us what’s happening:
the question asks to return an array as warm and sunny.Te indices for them are
2,3 respectively.But correct answer comes wit splice(2,4). why so???

Your code so far


function forecast(arr) {
  // change code below this line
return arr.slice(2,4);
}

// do not change code below this line
console.log(forecast(['cold', 'rainy', 'warm', 'sunny', 'cool', 'thunderstorms']));

The ending index is not included

please elaborate. my understanding is slice simple takes out the element at index passed out to it.

Please read the documentation that @EddieCornelious linked, you will find that your current understanding of slice is incorrect.
