For example, there executes the method fetchData() in SFC <script> tag in the tutorial Watchers. I want to know which step of lifecycle this method is executed in.
I might have found out the answer myself: ‘mounted’. Because the Options API edition of that tutorial uses mounted() to execute the method fetchData().
Sorry, I was wrong.
According to the official documentation:
Note that the
setup()hook of Composition API is called before any Options API hooks, even beforeCreate().
