Semicolons

Nobody has claimed this yet.

```
function yellIt(string) {
string = string.toUpperCase()
return makeMoreExciting(string)
}
```

That code has no semicolons. Well, it usually works, but not always:
```
a = 1 + 2
(3 + 4).toString()
```

Here is another (beautiful) example of that:
```
var a=3,b=3
[a,b]=[a*a,b*b]
console.log([a,b])
```
Another example:
```
x = 1 + 2
-1..toString()
```

I would suggest simply adding semicolons at the end of every statement. (Or, you could add a semicolon when they are needed. Though, explaining that would be more work and most likely would cause more screw ups)

Review the JavaScript examples covered by this lesson, starting with the semicolon examples and cited cases. Add semicolons consistently at statement ends, then verify that the examples still demonstrate the intended behavior.
