## README

# error-first

Convert async/await try/catch to `[error, result]`

## tl;dr

```ts
import errorFirst from 'error-first'

const [error, result] = await errorFirst(doSomething)
```

## Details

### Given an async operation
```ts
const addAsync = async (a, b) => {
    if (a == null || b == null) {
        throw 'Argument Error'
    }

    return a + b
}
```

### With error-first
```ts
import errorFirst from 'error-first'
// const errorFirst = require('error-first').default

const [error, result] = await errorFirst(addAsync(1, 2)) // [undefined, 3]
```

### With standard async/await
```ts
let result = null

try {
    result = await addAsync(1, 2)
} catch(error) {
    // Do something with error
}
```
