#30daysofVue - Day 3 - Vue Instance - Reactivity

Today I learned about reactivity in VueJs, and I'll explore it more tomorrow also.

Today I got to know that every item in data option is reactive and any change on them makes Vue to re render the template.

For every key-value pair, we declare in the data property of an instance, and the Vue library creates getters and setters on that property. These setters and getters work under the hood to track the data properties and cause the template to re-render when a change has been made.
