Hashes, also called associative arrays, are dictionary-like data structures which are similar to arrays.

The routing module provides URL rewriting in native Ruby. It's a way to redirect incoming requests to controllers and actions. It replaces the mod_rewrite rules. Best of all, Rails' Routing works with any web server. Routes are defined in app/config/routes.rb. Think of creating routes as drawing a Flowdock - Team Inbox With Chat.

Ruby Arrays An Array is just a list of items in order (like mangoes, apples, and oranges). Every slot in the list acts like a variable: you can see what object a particular slot points to, and you can make it point to a different object.You can make an array by using square brackets In Ruby, the first value in an array has index 0.
Depending on your use case this could be problematic if there are duplicate values. The method described above will return the equivalent or #rindex(last occurrence of value) To get #index equivalent results, meaning the hash returning the first index of the value you'd need to do something along the lines of reversing the array before creating the hash then subtracting the returned index Loops in Ruby are used to execute the same block of code a specified number of times. This chapter details all the loop statements supported by Ruby. Ruby while Statement Syntax while conditional [do] code end Executes code while conditional is true. A String object holds and manipulates an arbitrary sequence of bytes, typically representing characters.String objects may be created using String::new or as literals.. Because of aliasing issues, users of strings should be aware of the methods that modify the contents of a String object. Typically, methods with names ending in “!'' modify their receiver, while those without a “!'' return

Using block version in Ruby < 1.8.7 The block usage was added in 1.8.7, so to get the same functionality in an earlier version of Ruby, you need to utilize the find method. Here is a quick example: Ruby arrays are ordered, integer-indexed collections of any object. Each element in an array is associated with and referred to by an index. Array indexing starts at 0, as in C or Java. If all you need the hash for is membership, consider using a Set:. Set. Set implements a collection of unordered values with no duplicates. This is a hybrid of Array's intuitive inter-operation facilities and Hash's fast lookup. Depending on your use case this could be problematic if there are duplicate values.
