# Getting Started

Django Exceptions will attempt to flatten the validation messages into a single hierarchy, as otherwise the validation messages are infinitely nested, which makes it troublesome to render to HTML. Thus you are guanrateed to have a single array of all validation messages, with a `field` and `messages` key – both of which themselves are arrays.

```javascript

import parse from 'django-exceptions';

const data = await fromApi();

parse(data).forEach(x => {

    console.log('Field:', x.field);

    console.log('Messages:', x.messages);

});

```

In [React](https://github.com/facebook/react) you *might* do something like the following to render the messages:

```javascript

import parse from 'django-exceptions';

render() {

    

    return (

        


            {parse(this.props.messages).map(x => (

                
{x.field.join(' → ')}: {x.messages.join(', ')}

            ))}


        

    );


}

```
