Reference index of array with number containing variable

Question

If I can use array[i] inside of a for loop, why can't I use a different number-containing variable in a similar fashion, for example:

var arrayLength = array.length;  
var end = string.slice(array[arrayLength],stringLength);
        console.log(arrayLength);
        theRestArray.push(end);

Which is what's left over between the last index of the array and the end of a string. — Andrew

Arrays in javascript are zero-indexed, i.e, the first element is array[0] and the last is array[arrayLength-1]. So, use array[arrayLength-1] instead of array[arrayLength] and it should work.
