React-redux action creator

actionExample.js

// Example 1 with no payload
export function incrementCounter(){
  return {type:"INCREMENT_COUNTER"};
}

/*
  The action is only the object that is being return
  that is: {type:"INCREMENT_COUNTER"}
  Rest of the function is called Action creator - which creates the action
*/

// Example 2: action with addistional data (payload)

export function incrementCounterByIndex(index){
  return {type:"INCREMENT_COUNTER", payload:{index}};
}

/*
In this example we are transferring a payload object, with
a property of index.
Remember we are using ES6 convention becuase of which we need not
to write as index: index , LHS=RHS
