### How to use

[TypeScript Module Resolution Logic](https://www.typescriptlang.org/docs/handbook/module-resolution.html)
makes it quite easy. The `package.json` file contains `main` attribute that points to the generated
`dist/client.js` file and `typings` attribute that points to the generated `dist/client.d.ts` file.
You can also import this package as a module:

- Using `x-deep-merge` in a `TypeScript` file:

```ts
import { deepMerge } from '@empathyco/x-deep-merge'

const target = {}
const source1 = { a: 1 }
const source2 = { b: 2 }

deepMerge(target, source1, source2) // target = { a: 1, b: 2 }
```

- Another example

```ts
import { deepMerge } from '@empathyco/x-deep-merge'

const sources = [{ a: 1 }, { b: 2 }]
const mergedObject = deepMerge({}, ...sources) // mergedObject = { a: 1, b: 2 }
```
