Use-cases:
- If you want to make a conditional branch based on the result of a comparison of two types.

@example
```
import type {IsEqual} from 'type-fest';

// This type returns a boolean for whether the given array includes the given item.
// `IsEqual` is used to compare the given array at position 0 and the given item and then return true if they are equal.
type Includes<Value extends readonly any[], Item> =
	Value extends readonly [Value[0], ...infer rest]
		? IsEqual<Value[0], Item> extends true
			? true
			: Includes<rest, Item>
		: false;
```

/**
Create a type from an object type without certain keys.

We recommend setting the `requireExactProps` option to `true`.

This type is a stricter version of [`Omit`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-5.html#the-omit-helper-type). The `Omit` type does not restrict the omitted keys to be keys present on the given type, while `Except` does. The benefits of a stricter type are avoiding typos and allowing the compiler to pick up on rename refactors automatically.

This type was proposed to the TypeScript team, which declined it, saying they prefer that libraries implement stricter versions of the built-in types ([microsoft/TypeScript#30825](https://github.com/microsoft/TypeScript/issues/30825#issuecomment-523668235)).

@example
```
import type {Except} from 'type-fest';

type Foo = {
	a: number;
	b: string;
};

type FooWithoutA = Except<Foo, 'a'>;
//=> {b: string}

const fooWithoutA: FooWithoutA = {a: 1, b: '2'};
//=> errors: 'a' does not exist in type '{ b: string; }'

type FooWithoutB = Except<Foo, 'b', {requireExactProps: true}>;
//=> {a: number} & Partial<Record<"b", never>>

const fooWithoutB: FooWithoutB = {a: 1, b: '2'};
//=> errors at 'b': Type 'string' is not assignable to type 'undefined'.
```
