I've seen many times Vue instance is bind on body tag.
Other times this is bind on a div id
I'm asking when i should use body tag or an id tag (that limit the scope of the Vue instance).
Two examples:
new Vue({
el: 'body'
});
OR
new Vue({
el: '#a-div'
});

The key difference is that v-if conditionally renders elements and v-show conditionally displayselements. This means that v-if will actually destroy and recreate elements when the conditional is toggled. Meanwhile, v-show will always keep the element in the DOM and will only toggle its display by changing its CSS.
The v-bind directive is a Vuejs directive used to bind one or more attributes, or a component prop to an element. If that attribute is binded to our data defined in Vuejs instance then dynamically changes can be observed as data changes.
v-model is for two way bindings means: if you change input value, the bound data will be changed and vice versa. But v-bind:value is called one way binding that means: you can change input value by changing bound data but you can't change bound data by changing input value through the element.
Vuex is a state management pattern for vue. js. $t is the injected method from vue. js or Vue.
You should never use the body tag. In fact, it raises a warning to use the body tag.
Added a warning when mounting the root instance to body or html. This is no longer recommended in 2.0.
This is from the release notes, anyways it's incorrect, it raises an error.
