https://v1.vuejs.org/api/#debug 9/52
Details:
The data object for the Vue instance. Vue.js will recursively convert its properties into
getter/setters to make it “reactive”. The object must be plain: native objects, existing
getter/setters and prototype properties are ignored. It is not recommended to observe
complex objects.
Once the instance is created, the original data object can be accessed as vm.$data . The
Vue instance also proxies all the properties found on the data object.
Properties that start with _ or $ will not be proxied on the Vue instance because they
may conflict with Vue’s internal properties and API methods. You will have to access them
as vm.$data._property .
When defining a component, data must be declared as a function that returns the initial
data object, because there will be many instances created using the same definition. If we
still use a plain object for data , that same object will be shared by reference across all
instance created! By providing a data function, every time a new instance is created, we
can simply call it to return a fresh copy of the initial data.
If required, a deep clone of the original object can be obtained by passing vm.$data
through JSON.parse(JSON.stringify(...)) .
Example:

Type: Array | Object
Details:
A list/hash of attributes that are exposed to accept data from the parent component. It has
a simple Array-based syntax and an alternative Object-based syntax that allows advanced
var data = { a: 1 }
// direct instance creation
var vm = new Vue({
data: data
})
vm.a // -> 1
vm.$data === data // -> true
// must use function when in Vue.extend()
var Component = Vue.extend({
data: function () {
return { a: 1 }
}
})
