When parse object with an empty array it return []

[namantam1]

Is this expected behavior?

// when
stringify({arr: [1, 2]})
// returns: 'arr:\n  - 1\n  - 2\n'


// when
stringify({arr: []})
// returns: 'arr: []\n'

I was expecting blank array to be arr: \n.

Also, how can I omit blank array fields?

[] is the only available YAML representation of an empty array. The empty value you're expecting represents a null value.

To get what you want, I'd recommend using a replacer to replace empty arrays with undefined, which is ignored: https://eemeli.org/yaml/#yaml-stringify
