#30daysofVue - Day 7 - v-model
V-model binds the user input with the vue objects data model, as one change the other automatically get updated.
It takes the data property of vue instance as a single source of truth, as opposed to the HTML attributes like checked or selected.
To make the model update when the change event occurs, and not any time the user presses a key, you can use v-model.lazy instead of just v.model.
Working with input fields, v-model.trim is useful because it automatically removes whitespace.
And if you accept a number instead than a string, you can use v-model.number.
