JavaScript code - Exercise

Take a look at the following code. Copy it into the codelab tool http://bit.ly/codelabtool and try it out. What happens?

<html>
<script>
    var today = new Date(); // creates a new Date thing saved in a variable called today
    var day_of_week = today.getDay();
    alert(day_of_week);
</script>
<body>Hello everyone</body>
</html>

OK… Note that:

Say today is Thursday.

If Sunday is represented by 0, Monday by 1, Tuesday by 2 … then Thursday is represented by the number 4! Knowing that…

Now, how would you describe what this code is doing?

How can you edit this code so that, instead of showing a number in the alert, it shows “It’s Thursday!” if you run it on Thursday?

You should make it so that if you run it on Monday, it will show ‘It’s Monday!’, on Tuesday it will show ‘It’s Tuesday!’, and so on …

HINT: Remember conditional statements? If __ , then ??? … How can you frame those in English, write/draw out your idea, and then translate it to code? Tricky!
