Indentation is not significant (but two-character indentation is the de facto Ruby standard). Ruby doesn’t use braces to delimit the bodies of compound statements and definitions (such as methods and classes). Instead, you simply finish the body with the keyword end. The keyword return is optional, and if not present, the results of the last expression evaluated will be returned. 2 Data Types While everything in Ruby is an object, some of the data types in Ruby have special syntax support, in particular for defining literal values.

So-called tab completion is standard on Unix shells such as Bash and zsh. It allows you to type the first few characters of a filename, hit Tab , and have the shell look for and complete the name based on matching files. Version Control We keep all our work in a version control system (currently Git). We make a point of checking a new Rails project into Git when we create it and committing changes once we have passed the tests.
