Using parseInt() in a array.

In the video, the array had all number values for answers and used the parseInt() method to convert the string in to numbers.... What if I create a similar array, but with mixed strings and numeric values. would that be possible and what code?

It would certainly be possible, just leave off the "parseInt" calls. But you have to consider what the array is being used for.

I'd guess that if the current code converts everything with "parseInt", it's because the array values are used later in numeric computations and/or evaluations. If so, storing strings instead might cause the rest of the program to fail.
