| <script> | |
| var button = document.getElementById("myButton") | |
| function speak(){ alert("hi!") } // this is a function declaration, allowing 'speak' to be used anywhere in the code, even above this line. | |
| //you can also assign an "anonymous function" to a variable name, but this function can only be called below where it was assigned | |
