2,275 PointsHow come a set of string is equal to one slice?
When I wanted to slice from the word quick to fox, how come I am slicing the words and not the letters?
<script>
var first = ["The", "quick", "brown", "fox", "jumps"]
var second = ["over", "the", "lazy"];
var saying = first.concat("over", "the", "lazy","dog");
var shortSaying = saying.slice(1,4);
saying.slice()
var sayingString = saying;
</script>

605 PointsSince saying is an array of strings, it is the array that you're slicing when you retrieve ["quick", "brown", "fox"].
It can be confusing because arrays of strings and strings can both be sliced. Compare:
['a','b','c','d'].slice(1, 3) // equals ["b", "c"]
'abcd'.slice(1,3) // equals "bc"

12,548 PointsThe data stored in the variables first, second, and saying is an array, not a string. Therefore, when you use the slice method on saying, you are taking the values in positions 1, 2, and 3 of the array (so the words "quick", "brown", and "fox", since the position numbers in an array begin with the number 0). If instead you were using the slice method on a string, like "quick", then you would be slicing the characters. Does that make sense? Smile more:) Laura
