 * **Convention over Configuration** - Simple conventions help developers follow solid patterns and reduce the amount of code they have to write and maintain. It also means less fiddling with framework APIs and more focus on their app.
 * **Simple, But Not Simplistic** - Aurelia is simple to learn, but extremely powerful. Because of the simple, consistent design, developers are able to learn a very small set of patterns and APIs that unlock limitless possibilities.
 * **Promotes the "-ilities"** - Testability, maintainability, extensibility, learnability, etc. These are often referred to as the "-ilities". Aurelia's design helps developers naturally write code that exhibits these desirable characteristics.
-* **Amazingly Extensible** - Aurelia is higly modular and designed to be customized easily. Almost every aspect of Aurelia is extensible, meaning developers will never hit a roadblock or have to "hack" the framework to succeed.

 * **Web Standards Focused** - Focused on next generation JavaScript and Web Components, and avoiding unnecessary abstractions that obscure the underlying web, Aurelia is the cleanest and most standards-compliant framework today.
 * **Integrates Well with Others** - Because of the extensible design of Aurelia and a number of core technical considerations we made early on, it's easy to integrate Aurelia with any 3rd party library or framework. For example, you can easily integrate with jQuery, React, Polymer, Bootstrap, MaterializeCSS and much more.
 * **TypeScript Support** - Each Aurelia library is released with its own d.ts files. We also have official TypeScript beginner kits and production quality starter kits.
