-The <em>createSlice</em> function's <em>name</em> parameter defines the prefix which is used in the action's type values. For example, the <em>createNote</em> action defined later will have the type value of <em>notes/createNote</em>.

The <em>initialState</em> parameter defines the reducer's initial state. The <em>reducers</em> parameter takes the reducer itself as an object, of which functions handle state changes caused by certain actions. Note that the <em>action.payload</em> in the function contains the argument provided by calling the action creator:
