### 1. What will be the value of `b`?

    var r = undefined;
    a = b = c = 20;
    n = i = r;

### 2. Describe each part of a `for` loop structure.

### 3. Examine this `script example`.

    for(i = 0; i < n; i++){
      b = i;
    }

#### 3.1 Explain at least 3 things wrong with it.
#### 3.2 What will be the value of `b`?
### 4. After the following code has run what will be the value of `x`?

    var x = false && true && true && true && false || true;

### 5. After running the code below:

    var x = 0;

    function multiply(a, b){
      var x = a * b;
      return x;
    }

    var z = multiply(20, 10);

#### 5.1 What will be the value of `x`? 
#### 5.2 What will be the value of `z`?

### 6. After running the code below:

    (function(){
      b = 20;
      var a = 10 * b;
      return a;
    })();

#### 6.1 what will be the value of `b`?
#### 6.2 What will be the value of `a`?

### 7. What will be the value of `a`?

    a = 10;
    a /= 2;

### 8. What will be the value of `a['foo']`?

    var a = { bar: 10, baz: 20, foo: 40 };
    a.foo += a.bar;

### 9. What will be the value of `a[3]`?

    var a = "I ran all the way home";

### 10. What will be the value of `b[3]`?

    var b = "I ran all the way home".split(' ');

### 11. What will be the value of `m`?

    var m = /test/.test("I know this is a test");

### 12. After running the code below:

    Object.prototype.mush = function(){
      var b = 0, c = [];
      if(this instanceof Array){
        b = this.reduce(function(s,i){ return s + i; });
        c = this.map(function(i){ return b; });
      }
      return c;
    }

    a = [1,2,3,4,5,6,7];

    a.mush();

    b = a[2];

#### 12.1 What will be the value of `b`? 
#### 12.2 What will be the value of `a.mush()[2]`? 
#### 12.3 What will be the value of `b == a.mush()[2]`
