# Vuex
To manage the state of an application you should use [Vuex][vuex-docs].
_Note:_ All of the below is explained in more detail in the official [Vuex documentation][vuex-docs].
## Separation of concerns
Vuex is composed of State, Getters, Mutations, Actions and Modules.
When a user clicks on an action, we need to `dispatch` it. This action will `commit` a mutation that will change the state.
_Note:_ The action itself will not update the state, only a mutation should update the state.

If you need to add a new format, because other parts of the code could benefit from it,
you'll need to add it to [en.yml](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/config/locales/en.yml) file.
1. **Through `strftime`**, i.e. `milestone.start_date.strftime('%b %-d')`. We use `strftime` in case none of the formats
defined on [en.yml](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/config/locales/en.yml) matches the date/time
specifications we need, and if there is no need to add it as a new format because is very particular (i.e. it's only used in a single view).

The reasoning behind this is that in some languages words change depending on context. For example in Japanese は is added to the subject of a sentence and を to the object. This is impossible to translate correctly if we extract individual words from the sentence.
