What do parenthesis surrounding brackets in the return statement of an ES6 arrow function do?

Question

For example in redux actions, I\'ve seen in someone\'s code:

export const updateMessage = text => {
   return (dispatch) => {
     dispatch(updateChatMess         


        

Answer 1

If you wrap the brackets with parenthesis you are making your function return an object literal (thus you don't need the return keyword). If you don't use parenthesis you have to use the return keyword.
