- the
slice()
function must be used to return an array consisting of only warm
and sunny
.
- Therefore, two parameters must be passed to the
slice()
function. The first parameter must be the index you would like the substring to start at. The second parameter must be the index at which the substring ends.
- Note: The second parameter will end the substring at that exact index.
Example:
return arr.slice(1, 4);
/* This will return a substring consisting of indexs [1,2,3]
Note: arr[4] is NOT included. */
