Thank you very much Mr. Ian let slicedForecast = arr.slice(2, 4);
return slicedForecast;
answer is [ 'warm', 'sunny' ]

and if I do let slicedForecast = arr.slice(2, 5);
return slicedForecast; I will get the [ 'warm', 'sunny', 'cool']

i passed with

arr = arr.slice(2, 4);

im confused why sunny is 4 when isn't it 3 since count starts from 0?
