1.An array uses indices and a hash uses "keys"
2.It's a test that simulates a browser accessing our application.
3.Red, Green, Refactor,Red refers to writing a failing test,Green refers to writing a passing test Once we have a passing test we are free to refactor the code.

Describe a "symbol" in Rails?
1.Ruby complains if we try to evaluate an undefined local variable, but issues no such complaint for an instance variable; instead, instance variables are nil if not defined
2.Symbols look kind of like strings, but prefixed with a colon instead of surrounded by quotes. For example, :name is a symbol. You can think of symbols as basically strings without all the extra baggag
3.An array uses indices and a hash uses "keys"

Name two ways to indicate a "block" in Rails
1.This maps requests for the URL /pages/home to the home action in the Pages controller.
2.The request hits the rails router which dispatches to the proper controller action. In this case, it goes to the index action in the Users controller.
3. Curly braces or do..end. It's best to use curly braces for short one-line blocks and the do..end for mult-iline blocks.
4.When the order matters, use an array.

what are the main principles of REST?
1.1. all important data is a resource, 2. every resource has a proper name (URL), 3. you can perform a standard set of operations on resources (usually CRUD), 4. client and server talk statelessly

3.a script that alters the structure of the underlying database
4.no. arrays just keep references to objects stored in memory.
