| // A short snippet for detecting versions of IE in JavaScript | |
| // without resorting to user-agent sniffing | |
| // ---------------------------------------------------------- | |
| // If you're not in IE (or IE version is less than 5) then: | |
| // ie === undefined | |
| // If you're in IE (>=5) then you can determine which version: | |
| // ie === 7; // IE7 | |
| // Thus, to detect IE: | |
| // if (ie) {} |
| //------------------------------------------------------------------------------------------------------------------ | |
| // YOUR CODE: Create your Zoo "object literal" and Animal "constructor" and "prototypes" here. | |
| //------------------------------------------------------------------------------------------------------------------ | |
| Zoo = { | |
| init: function(animals) { | |
| Zoo = new Array(animals); | |
| } | |
| }; |

In the following scenario, we have the following apps on the Heroku server:
In addition, each developer has a local development environment.
The goal is to move production data over to the staging server, and also provide production data to each of the developers. Here's what we will do.
#Stakeout
Congratulations! You are the new elite hacker in a group of villainous ne'er-do-wells.
Luckily this group is more saavy than your last band of ruffians, and they are looking to software (and you) to improve their take. The con man for the team, has gone door-to-door down each street posing as a termite inspector so he could covertly total the valuable goods in each house. Normally the gang would just rob all the valuable homes, but there's a catch! Whenever a house is robbed in this wealthy neighborhood, the police watch it and the neighboring houses for months.
| # This is a simple refactoring exercise. | |
| # | |
| # What to do? | |
| # | |
| # 1. Look at the code of the class CorrectAnswerBehavior | |
| # 2. Try to see what it does by running `ruby refactoring_example.rb` | |
| # 3. Record characterisation tests by running `ruby refactoring_example.rb --record` | |
| # 4. Make the code beautiful;) | |
| # 5. You are allowed to modify only the code between markers (REFACTORING START/REFACTORING END). | |
| # 6. Test must pass! You can run them with command `ruby refactoring_example.rb --test` |
