Using Vue Dev Tools and Testing Your SPA Chapter 12Drilling down into each component, we can access individual data objects and computed

console.log() statements.
Viewing Vuex mutations and time-travel
Navigating to the next tab, Vuex, allows us to watch store mutations taking place in real
time. Every time a mutation is fired, a new line is created in the left-hand panel. This
element allows us to view what data is being sent, and what the Vuex store looked like
before and after the data had been committed.
