watch() called with an array returns the defaultValues for falsy values

[dkusano]

When watch() is called with an array of field names, it returns the defaultValues for fields their values are empty string or false. It should returns empty values, not default values.

This behavior doesn't occurs when watch() is called with single field name or no arguments.

Here is an example code.

When watch() is called with an array of field names, it returns the defaultValues for fields their values are empty string or false.

This is the expected behavior.

The example you share they have the same output.

watch array: {"name":"default name","agree":true}

watch all: {"name":"default name","agree":true}

I'm sorry I didn't make it clear enough.

In the example, when you input empty string and checkbox off, watch(["name", "agree"]) and watch() behave different.

watch array: {"name":"default name","agree":true}

watch all: {"name":"","agree":false}
