title: Javascript Array Index not working properly
body: <p>I am currently trying to make a little prompt game that displays questions based on the category and difficulty selected by the user. I am trying to make this using the least code that I can so its most efficient. </p>
  
  <p>Currently what is happening, is I am saving the category in a variable called category and the difficulty value in an variable called difficulty. When I try to access my array I use <code>category[difficulty].question</code> as I have named my arrays according to their category. </p>
  
  <p>However, instead of indexing the proper element, it tries to spell the word of the category. i.e. if the category is geography and the difficulty is easy, I am trying to access <code>geography[0].question</code> by using <code>category[difficulty].question</code>. But instead I get the first letter of the word geography so all that displays in the console log is the string letter g. </p>
  
  <p>Can anyone explain why this is happening, and propose a solution.</p>
  
  <p>p.s. I know switch statements aren't commonly used anymore, but this is an assignment and I am required to use them.</p>
