A checkbox can be linked directly to a variable in your Vue instance.
This is two-way: it can make your app interactive if you want.
If you click on the checkbox, it changes the value in the Vue instance.
The variable also changes in your template.
Create a html template. Inside the template create your app in a div.
Then define the checkbox and link the model with v-model.
In your Vue instance, create the variable you defined in v-model previously.
Once you load it, it will show the value of the variable depending on the checkbox state.
