-## Interfaces over type alias
+## Types over interfaces
 
-Do not use `type`, but rather use `Interfaces`. `type` cannot be extended, and a class cannot implement it.
+Using `type` aliases in TypeScript offers several advantages over `interfaces`:
 
-> "In general, use what you want ( type alias / interface ) just be consistent"
-> "always use interface for public API's definition when authoring a library or 3rd party ambient type definitions"
->
-> -   https://medium.com/@martin_hotell/interface-vs-type-alias-in-typescript-2-7-2a8f1777af4c
+- **Flexibility with Complex Types**: `type` supports defining unions, intersections, and other complex type constructs that `interfaces` cannot handle. For example:
 
-`Interface` is generally preferred over `type`: https://stackoverflow.com/questions/37233735/typescript-interfaces-vs-types
+  ```typescript
+  type StringOrNumber = string | number;
+  type Combined = TypeA & TypeB;
+  ```
 
-**Do not:**
+- **Support for Primitive Types**: `type` can alias primitive types (e.g., `type ID = string`), while `interfaces` are limited to object shapes.
+- **Tuple and Array Types**: `type` allows defining tuples and specific array types easily (e.g., `type Point = [number, number]`), which `interfaces` cannot represent.
+- **Utility Types Compatibility**: `type` works seamlessly with TypeScript's utility types (e.g., `Partial<T>`, `Pick<T, K>`), enabling more expressive type transformations.
+- **Functional Programming**: `type` is ideal for functional programming patterns, such as defining function signatures or mapped types, due to its versatility.
+- **No Declaration Merging**: Unlike `interfaces`, type does not support declaration merging, which can prevent accidental type extensions and ensure predictable type definitions.
+- **Consistent Pattern**: This project uses `type` for all type definitions, so using `type` for all type definitions maintains consistency and readability across the codebase.
