console.log("beforeCreate")
},

// init events
created() {
console.log("created")
// have access to data and props
// good time to fetch data and manipulate data on the component
},
// check if there is an "el" option and render it.
// else check if there is a template and render it but not show yet.
beforeMount() {
console.log("beforeMount")
// finish render the template and its child component
// good time to manipulate data that came back from child component
},
// render the template to the real DOM
mounted() {
console.log("mounted")
// the template is render and printed on the real DOM
// if you manipulate the data here its effect on the view that already printed
},
beforeUpdate() {
console.log("beforeUpdate")
// just before any update of the component happens
// good time to debug what the status before the change
},
// the update happens
updated() {
console.log("updated")
// good time to debug what changed
},
beforeDestroy() {
console.log("beforeDestroy")
// component before unmounted, time for update the things that happens on this component
},

destroyed() {
console.log("destroyed")
// component unmounted, time for clean ups
}
