How can I specify what will happen after a button was clicked?

Question

When I was reading a HTML lesson, I saw a paragraph containing a "<button>" word. Then I entered the Code Playground and wrote an experimental (private) code. I want to specify what will happen when the button was pressed. Could someone help me with this?

You're halfway through the JavaScript course. Complete it and you will get what you need :)

<button onclick="doSomething()" >

function doSomething(){
alert("hello");

}
