9. Using Javascript, please write a function foo, that takes two arguments, an array and a number, and returns true if the length of the array is equal to the second argument? E.g. `foo([1, 2, 3], 3)` would return true.
    **Answer:**
    ```javascript
    function foo(x, y) {
      if (x.length == y) {
        return true;
      }
      else {
        return "Array length is not equal to " + y
      }
    };

    foo([1, 2, 3], 3);

    ```

10. Write a loop in Javascript, iterating over the array [1, 2, 3, 4] printing out if the element is either the first element (print `first - `), the last element (print `last`) or neither first or last element (print `not first or last -`). E.g. the expected output would be (`first - not first or last - not first or last - last`).
    **Answer:**
    ```javascript
    function loop(n) {
      for (i = 0; i < n.length; i++) {
        //first element
        if (i === 0) {
          console.log('first - ');
        }
        //last element
        else if (i === (n.length - 1)) {
          console.log('last');
        }
        //neither first or last element
        else {
          console.log('not first or last -');
        }
      }
    };

    var test = [1, 2, 3, 4, 5]
    loop(test);

    ```

11. Print all numbers from 15 - 0 to the console using a for loop in JS.
    **Answer:**
    ```javascript
    function printNum() {
      for (n = 15; n >= 0; n--) {
        console.log(n);
      }
    };

    printNum();

    ```

12. What would the console print in following example
    ```javascript
    function outer(input) {
      var a = input;

      function inner(multiplier) {
        console.log(a * multiplier);
      }

      return inner;
    }

    var firstResult = outer(9);
    firstResult(10);
    ```

    **Answer:**
    It would print 90.

13. Add the missing code to print "this is A" to the console by accessing the property from the JS object literal.
    ```javascript
    var someObject = {b : "some test", a : "this is A"};
    console.log("*Your code here*");
    ```

    **Answer:**
    ```javascript
    var someObject = {b : "some test", a : "this is A"};
    console.log(someObject.a);

    ```
