VUE父子組件生命週期執行順序?

1.  加載渲染過程  
    `父beforeCreate->父created->父beforeMount->子beforeCreate->子created->子beforeMount->子mounted->父mounted`
2.  子組件更新過程  
    `父beforeUpdate->子beforeUpdate->子updated->父updated`
3.  父組件更新過程  
    `父beforeUpdate->父updated`
4.  銷燬過程  
    `父beforeDestroy->子beforeDestroy->子destroyed->父destroyed`
