What are JS framework lifecycles for?

Question

Frontend

The question is in the title. Can't understand what is the practical application of these life cycles?
Well, the page goes through the instantiation stage, well, you changed some text on the page, thereby calling the "updated" hook (in vue, so), what do I care?
Give a practical example, please.

Answer 1

So that everyone understands what can / cannot be done at a certain moment and how it works.
So that there are no questions why this.$el does not work in beforeCreate/created.
