Collection of reusable query filters. As your application grows you may end up using the same filtering logic across many queries. You may want to define some general filters that can be reused and composed into more complex queries. Some have built-in methods for doing this e.g. you can define a model scope in or create a custom queryset method in . Using conditions where object literals can be represented by the and operator gives us a. Convenient way to define a colle photo editing servies ction of reusable filters. Strongly typed functions with inferred return types Sometimes you may want to assert that a function matches a special function signature such as a component or remix loader function. In cases like loaders you also want to infer by function. Previously it was difficult to achieve both goals at the same time. Using the operator we can now ensure that the function is signed with the special function. Name without expanding its return type. Let's look at an example of using a loader to return some data from. Here the operator does three things. Make sure our function is compatible with the signature. Infer the function's parameter types from the signature so we don't have to manually annotate them. Infer that our function returns from An object wraps up its related objects and allows you to easily obtain type-safe .
