# Types

Explicit types are necessary. Always use explicitly defined types and avoid
anonymous types when possible. Only use interfaces when for module augmentation.
Otherwise, use `type` definitions since they can be composed via discriminated
unions. DO NOT write classes, ever. Instead of a class, write a type and export
functions that take an instance of that type as the _last_ argument (fp style).

```typescript
// GOOD
export type MyTypeName = {
  prop: string;
  value: int;

  nestedThings: NestedType[];
};

export type NestedType = {
  id: string;
};
```

```typescript
// BAD
export interface MyTypeName { // interface instead of type
  prop: string;
  value: int;

  nestedThings Array<{ // anonymous type
    id: string;
  }>;
};
```

# Functions

Always use `const fn = () => {}` definitions over `function fn() {}`
definitions unless you use `this` within the function. Always prefer
"fp style" function declarations; args first data last. This is more
composable.
