Test your skills: Conditionals
==============================

The aim of this skill test is to assess whether you've understood our Making decisions in your code — conditionals article.

**Note:** You can try solutions by downloading the code and putting it in an online editor such as CodePen, JSFiddle, or Glitch.
 If there is an error, it will be logged in the results panel on the page or into the browser's JavaScript console to help you.


If you get stuck, you can reach out to us in one of our communication channels.

Conditionals 1
--------------

In this task you are provided with two variables:

* `season` — contains a string that says what the current season is.
* `response` — begins uninitialized, but is later used to store a response that will be printed to the output panel.

We want you to create a conditional that checks whether `season` contains the string "summer", and if so assigns a string to `response` that gives the user an appropriate message about the season. If not, it should assign a generic string to `response` that tells the user we don't know what season it is.

To finish off, you should then add another test that checks whether `season` contains the string "winter", and again assigns an appropriate string to `response`.

Conditionals 2
--------------

For this task you are given three variables:

* `machineActive` — contains an indicator of whether the answer machine is switched on or not (`true`/`false`)
* `score` — Contains your score in an imaginary game. This score is fed into the answer machine, which provides a response to indicate how well you did.
* `response` — begins uninitialized, but is later used to store a response that will be printed to the output panel.

You need to create an `if...else` structure that checks whether the machine is switched on and puts a message into the `response` variable if it isn't, telling the user to switch the machine on.

Inside the first `if...else`, you need to nest another `if...else` that puts appropriate messages into the `response` variable depending on what the value of score is — if the machine is turned on. The different conditional tests (and resulting responses) are as follows:

* Score of less than 0 or more than 100 — "This is not possible, an error has occurred."
* Score of 0 to 19 — "That was a terrible score — total fail!"
* Score of 20 to 39 — "You know some things, but it\'s a pretty bad score. Needs improvement."
* Score of 40 to 69 — "You did a passable job, not bad!"
* Score of 70 to 89 — "That\'s a great score, you really know your stuff."
* Score of 90 to 100 — "What an amazing score! Did you cheat? Are you for real?"

Try updating the live code below to recreate the finished example. After you've entered your code, try changing `machineActive` to `true`, to see if it works.

Conditionals 3

For the final task you are given four variables:

* `machineActive` — contains an indicator of whether the login machine is switched on or not (`true`/`false`).
* `pwd` — Contains the user's login password.
* `machineResult` — begins uninitialized, but is later used to store a response that will be printed to the output panel, letting the user know whether the machine is switched on.
* `pwdResult` — begins uninitialized, but is later used to store a response that will be printed to the output panel, letting the user know whether their login attempt was successful.

We'd like you to create an `if...else` structure that checks whether the machine is switched on and puts a message into the `machineResult` variable telling the user whether it is on or off.

If the machine is on, we also want a second conditional to run that checks whether the `pwd` is equal to `cheese`. If so, it should assign a string to `pwdResult` telling the user they logged in successfully. If not, it should assign a different string to `pwdResult` telling the user their login attempt was not successful. We'd like you to do this in a single line, using something that isn't an `if...else` structure.
