Title: Fix first two code samples.

The original sample below will really give out a Reference Error since the function wasn't called in the first place.

```js
function myFunc() { x = 5; }
console.log( x ); // 5
```
It should be:
```js
function myFunc() { x = 5; }
myFunc()
console.log( x ); // 5
```
