You may have already guessed how the Vue object would look. Efficiently copies objects by reusing existing nested objects whose properties aren’t changed Operates differently depending whether built for development or production development - objects are frozen; overrides methods that normally mutate to throw production - assumes code has been tested in development mode.

However, as our application grows in scale, the store can get really bloated. commit to commit a mutation, or access the state and getters via context. Whatever is typed will become the message field in the event. We will be using ES2015 in the code samples in the guide. js to take advantage of its granular reactivity system for efficient updates.
