type-fest/source/unknown-record.d.ts

A collection of essential TypeScript types

/**
Represents an object with `unknown` value. You probably want this instead of `{}`.

Use case: You have an object whose keys and values are unknown to you.

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

function toJson(object: UnknownRecord) {
	return JSON.stringify(object);
}

toJson({hello: 'world'});
//=> '{"hello":"world"}'

function isObject(value: unknown): value is UnknownRecord {
	return typeof value === 'object' && value !== null;
}

isObject({hello: 'world'});
//=> true

isObject('hello');
//=> false
```
