# Type-Fest

> A collection of essential TypeScript types that should have been built-in. It provides a number of utility types that can be used to create new types from existing ones, such as type guards, type predicates, and type transformations.

## Features
- Utility types for creating new types from existing ones
- Type guards and type predicates for checking type safety
- Type transformations for modifying existing types

## Quick Start
```
npm install type-fest
import type {Except} from 'type-fest';
type Foo = {
  unicorn: string;
  rainbow: boolean;
};
type FooWithoutRainbow = Except<Foo, 'rainbow'>;
//=> {unicorn: string}
```
