why I cant get value.lenght?

There is an assumption that it is because of the quotes. In that case all the same a question - how to correct it?

It doesn't parse

I tried using Object.keys

What are your ideas about this?

It's not at all clear what you're trying to do here, or what the question is — Robin Zigmond

Your property is an Object and not an array.

Get the length of the root of your object.

var length_object = Object.keys(your_object).length;

Get the length of your 'values'

var length_values = your_object['value'].length;

Assigning this object to a variable solved the issue. Setting it to:

var obj = { /* your object here */ }
console.log(obj.value.length) // returns 2

Because the way it is presented in your question, you did not assign that object to anything, hence you can not access the property of value and its length
