## NS interface

Collection of all functions passed to scripts

**Signature:**

```typescript
export interface NS 
```

## Remarks

<b>Basic usage example:</b>

```js
export async function main(ns) {
 // Basic ns functions can be accessed on the ns object
 ns.getHostname();
 // Some related functions are gathered under a sub-property of the ns object
 ns.stock.getPrice();
 // Most functions that return a promise need to be awaited.
 await ns.hack('n00dles');
}
```
