 In JavaScript, 
 dependency injection frameworks tend to be less common because of its flexible nature.
 However, with the increasing popularity of TypeScript –which provides strict typings for JavaScript–,
 the need for dependency injection is increasing.
-Still, multiple frameworks are available, such as [BottleJS](https://github.com/young-steveo/bottlejs), [Wire](https://github.com/cujojs/wire), and [Electrolyte](https://github.com/jaredhanson/electrolyte), all backed by rather small communities.

 Unlike standard JavaScript,
 it requires the developer to define interfaces and types via TypeScript,
