 In Nest, thanks to TypeScript capabilities, it's extremely easy to manage dependencies because they are resolved just by type. In the example below, Nest will resolve the `catsService` by creating and returning an instance of `CatsService` (or, in the normal case of a singleton, returning the existing instance if it has already been requested elsewhere). This dependency is resolved and passed to your controller's constructor (or assigned to the indicated property):

 #### Scopes
 
-Providers normally have a lifetime ("scope") synchronized with the application lifecycle. When the application is bootstrapped, every dependency must be resolved, and therefore every provider has to be instantiated. Similarly, when the application shuts down, each provider will be destroyed. However, there are ways to make your provider lifetime **request-scoped** as well. You can read more about these techniques [here](/fundamentals/injection-scopes).

 #### Custom providers
 
-Nest has a built-in inversion of control ("IoC") container that resolves relationships between providers. This feature underlies the dependency injection feature described above, but is in fact far more powerful than what we've described so far. There are several ways to define a provider: you can use plain values, classes, and either asynchronous or synchronous factories. More examples are provided [here](/fundamentals/dependency-injection).
