## createTimeout() <a href="#createtimeout" id="createtimeout"></a>

A promisified version of the `setTimeout` function:

```typescript
import { createTimeout } from "@corets/promise-helpers"

await createTimeout(2000)
```

## createPromise() <a href="#createpromise" id="createpromise"></a>

Create a promise that you can pass around without specifying the resolve function upfront:

```typescript
import { createPromise } from "@corets/promise-helpers"

const runWhenResolved = async (promise: Promise<any>) => {
  try {
    const result =  await promise
    console.log("promise resolved with:", result)
  } catch (err) {
    console.error("an error was thrown from promise:", err)
  }
}

const promise = createPromise()

// pass promise to another function
runWhenResolved(promise)

promise.resolve("some data")
// or
promise.reject("reason...")
```
