Functional `try-catch` wrapper for `promises`.

## Install

```
npm i try-to-catch
```

## API

### tryToCatch(fn, [...args])

Wrap function to avoid `try-catch` block, resolves `[error, result]`;

### Example

Simplest example with `async-await`:

```js
import {tryToCatch} from 'try-to-catch';

const reject = Promise.reject.bind(Promise);
await tryToCatch(reject, 'hi');
// returns
// [ Error: hi]
```

Can be used with functions:

```js
import {tryToCatch} from 'try-to-catch';

await tryToCatch(() => 5);
// returns
[null, 5];
```

Advanced example:

```js
import {readFile, readdir} from 'node:fs/promises';
import {tryToCatch} from 'try-to-catch';

const [error, data] = await tryToCatch(read, process.argv[2]);

if (error) {
    console.error(error);
    process.exit(1);
}

console.log(data);

async function read(path) {
    const [error, data] = await tryToCatch(readFile, path, 'utf8');
    
    if (!error)
        return data;
    
    if (error.code !== 'EISDIR')
        return error;
    
    return await readdir(path);
}
```
