Convert a union type to an intersection type using [distributive conditional types](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-8.html#distributive-conditional-types).

Inspired by [this Stack Overflow answer](https://stackoverflow.com/a/50375286/2172153).

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

type Union = {the(): void} | {great(arg: string): void} | {escape: boolean};

type Intersection = UnionToIntersection<Union>;

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

class CommandOne {

		a1: () => undefined,
		b1: () => undefined,
	}
}

class CommandTwo {
	commands: {
		a2: (argA: string) => undefined,
		b2: (argB: string) => undefined,
	}
}

const union = [new CommandOne(), new CommandTwo()].map(instance => instance.commands);
type Union = typeof union;
//=> {a1(): void; b1(): void} | {a2(argA: string): void; b2(argB: string): void}

type Intersection = UnionToIntersection<Union>;
//=> {a1(): void; b1(): void; a2(argA: string): void; b2(argB: string): void}
```

Sometimes it is desired to pass a value as a function argument that has a different type. At first inspection it may seem assignable, and then you discover it is not because the `value`'s type definition was defined as an interface. In the following example, `fn` requires an argument of type `Record<string, unknown>`. If the value is defined as a literal, then it is assignable. And if the `value` is defined as type using the `Simplify` utility the value is assignable.  But if the `value` is defined as an interface, it is not assignable because the interface is not sealed and elsewhere a non-string property could be added to the interface.

If the type definition must be an interface (perhaps it was defined in a third-party npm package), then the `value` can be defined as `const value: Simplify<SomeInterface> = ...`. Then `value` will be assignable to the `fn` argument.  Or the `value` can be cast as `Simplify<SomeInterface>` if you can't re-declare the `value`.

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

interface SomeInterface {
	foo: number;
	bar?: string;
	baz: number | undefined;
}

type SomeType = {
	foo: number;
	bar?: string;
	baz: number | undefined;
};

const literal = {foo: 123, bar: 'hello', baz: 456};
const someType: SomeType = literal;
const someInterface: SomeInterface = literal;

function fn(object: Record<string, unknown>): void {}

fn(literal); // Good: literal object type is sealed
fn(someType); // Good: type is sealed
fn(someInterface); // Error: Index signature for type 'string' is missing in type 'someInterface'. Because `interface` can be re-opened
fn(someInterface as Simplify<SomeInterface>); // Good: transform an `interface` into a `type`

/**
Omit any index signatures from the given object type, leaving only explicitly defined properties.

This is the counterpart of `PickIndexSignature`.

Use-cases:
- Remove overly permissive signatures from third-party types.

This type was taken from this [StackOverflow answer](https://stackoverflow.com/a/68261113/420747).

It relies on the fact that an empty object (`{}`) is assignable to an object with just an index signature, like `Record<string, unknown>`, but not to an object with explicitly defined keys, like `Record<'foo' | 'bar', unknown>`.

(The actual value type, `unknown`, is irrelevant and could be any type. Only the key type matters.)

```
const indexed: Record<string, unknown> = {}; // Allowed

const keyed: Record<'foo', unknown> = {}; // Error
// => TS2739: Type '{}' is missing the following properties from type 'Record<"foo" | "bar", unknown>': foo, bar
```

Instead of causing a type error like the above, you can also use a [conditional type](https://www.typescriptlang.org/docs/handbook/2/conditional-types.html) to test whether a type is assignable to another:

```
type Indexed = {} extends Record<string, unknown>
	? '✅ `{}` is assignable to `Record<string, unknown>`'
	: '❌ `{}` is NOT assignable to `Record<string, unknown>`';
// => '✅ `{}` is assignable to `Record<string, unknown>`'

type Keyed = {} extends Record<'foo' | 'bar', unknown>
	? "✅ `{}` is assignable to `Record<'foo' | 'bar', unknown>`"
	: "❌ `{}` is NOT assignable to `Record<'foo' | 'bar', unknown>`";
// => "❌ `{}` is NOT assignable to `Record<'foo' | 'bar', unknown>`"
```

Using a [mapped type](https://www.typescriptlang.org/docs/handbook/2/mapped-types.html#further-exploration), you can then check for each `KeyType` of `ObjectType`...

```
import type {OmitIndexSignature} from 'type-fest';

type OmitIndexSignature<ObjectType> = {
	[KeyType in keyof ObjectType // Map each key of `ObjectType`...
	]: ObjectType[KeyType]; // ...to its original value, i.e. `OmitIndexSignature<Foo> == Foo`.
};
```

...whether an empty object (`{}`) would be assignable to an object with that `KeyType` (`Record<KeyType, unknown>`)...

```
import type {OmitIndexSignature} from 'type-fest';

type OmitIndexSignature<ObjectType> = {
	[KeyType in keyof ObjectType
		// Is `{}` assignable to `Record<KeyType, unknown>`?
		as {} extends Record<KeyType, unknown>
			? ... // ✅ `{}` is assignable to `Record<KeyType, unknown>`
			: ... // ❌ `{}` is NOT assignable to `Record<KeyType, unknown>`
	]: ObjectType[KeyType];
};
```

If `{}` is assignable, it means that `KeyType` is an index signature and we want to remove it. If it is not assignable, `KeyType` is a "real" key and we want to keep it.

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

interface Example {
	// These index signatures will be removed.
	[x: string]: any
	[x: number]: any
	[x: symbol]: any

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)).

// `Omit` clearly doesn't behave as expected in this case:

//=> type PostPayload = { [x: string]: string; [x: number]: string; }

// In situations like this, `Except` works better.
// It simply removes the `email` key while preserving all the other keys.
