• Generic, interpreted, reflective, with garbage collection
• Optimized for people rather than computers
• Everything is an object. There are no primitive types.
• More powerful than Perl, more object oriented than Python

Best practices: MVC, DRY, Testing.
• Convention over Configuration.
• Integrated AJAX support. Web services with REST.
• Almost everything in Rails is Ruby code (SQL and JavaScript
are abstracted).
• Three environments- Development, Production, Testing.
• Ruby - less and more readable code, shorter development
times, simple but powerful, no compilation cycle.
• Metaprogramming.
• CoffeeScript, JQuery, Sass, Haml, JSON & HTTP Streaming.

Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance. Sass has two syntaxes. The new main syntax (as of Sass
3) is known as “SCSS” (for “Sassy CSS”) Every valid CSS3 stylesheet is valid SCSS as well.
/* .scss */$blue: #3bbfce;$margin: 16px; /* CSS */.content-navigation { .content-navigation { border-color: $blue; border-color: #3bbfce; color:darken($blue, 9%); } color: #2b9eab; }
.border { .border { padding: $margin / 2; padding: 8px; margin: $margin / 2; margin: 8px;
border-color: $blue; } border-color: #3bbfce; }
