* We could use one screen for the code and the other for the HTML page that would be displayed so they could see them side by side

# Variables

* We will provide an HTML file:
```html
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>Javascript Tutorial</title>
</head>
<body>
<button type="button">Click me!</button>
</body>
</html>
```
* We will add an `onlclick` event to the button and add the function between script tags in the body:
```html
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>Javascript Tutorial</title>
</head>
<body>
<button type="button" onclick="sayHello()">Click me!</button>

<script>
function sayHello() {
alert("Hello, World!");
}
</script>
</body>
</html>
```
* Then, we'll take it up a notch and introduce arguments.
```html
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>Javascript Tutorial</title>
</head>
<body>
<button type="button" onclick="sayHello('World')">Click me!</button>

<script>
function sayHello(x) {
var name = x;
alert("Hello, " + name + "!");
}
</script>
</body>
</html>
```
* But what if we want to ask them what their name is? We can add a prompt.
```html
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>Javascript Tutorial</title>
</head>
<body>
<button type="button" onclick="sayHello()">Click me!</button>

<script>
function sayHello() {
var name = prompt("Please enter your name");
alert("Hello, " + name + "!");
}
</script>
</body>
</html>
```
* Since pressing Cancel results in the alert saying "Hello, null!" we can include an if statement:
```html
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>Javascript Tutorial</title>
</head>
<body>
<button type="button" onclick="sayHello()">Click me!</button>

<script>
function sayHello() {
var name = prompt("Please enter your name");
if (name != null) {
alert("Hello, " + name + "!");
}
}
</script>
</body>
</html>
```
* Addition of the confirm() option:
```html
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>Javascript Tutorial</title>
</head>
<body>
<button type="button" onclick="sayHello()">Click me!</button>

<script>
function sayHello() {
var cancelled = false;
while(cancelled == false) {
var name = prompt("Please enter name: ");
if (name == "" || name == null) {
cancelled = confirm("Are you sure you do not want to enter your name?");
} else {
cancelled = true;
alert("Hello, " + name + "!");
}
}
}
</script>
</body>
</html>
```
