Javascript noob here.... I am trying to build a site that will help my kids read predefined sentences from a select group, then when a button is clicked it will display one of the sentences. Is an array the best option for this?

For example, I have this array (below) and on the click of a button I would like one of these sentences to appear on the page.

<script type="text/javascript">
Sentence = new Array()
Sentence[0]='Can we go to the park.';
Sentence[1]='Where is the orange cat? Said the big black dog.';
Sentence[2]='We can make the bird fly away if we jump on something.'
Sentence[3]='We can go down to the store with the dog. It is not too far away.'
Sentence[4]='My big yellow cat ate the little black bird.'
Sentence[5]='I like to read my book at school.'
Sentence[6]='We are going to swim at the park.'
</script>

Again, is an array the best for this and how could I get the sentence to display? Ideally I would want the button to randomly select one of these sentences but just displaying one of them for now would help.

Thanks
