# early-return
Helper to facilitate early returns across function stack in JavaScript.
```ts
import { early, earlyReturn } from 'early-return'
function handler() {
early(1, true) // Will return, value 1.
early(2, false) // Will be skipped, no value.
early(3) // Will return, value 3.
}
const value = earlyReturn(handler)
```
This plugin is especially useful when integrated directly into frameworks, so that the overhead of wrapping functions isn't necessary. The following example shows how it simplifies JSX components.
```tsx
function MyComponent() {
if (Store.loading) {
return
Loading...
}
if (Store.error) {
return Error!
}
return Hello World!
}
```
```tsx
function MyComponent() {
early(
Loading...
, Store.loading)
early(Error!
, Store.error)
return Hello World!
}
```
Most importantly `early` can also be called in nested methods forcing the execution of all earlier methods to stop as well.
