How do you use the map in the lightning component?

({ doInit: function(component, event, helper) {
var action = component. get(‘c.getMyMap’); action. …
var state = response. getState(); if (state === “SUCCESS”) {
//set response value(map) in myMap attribute on component. component. set(‘v.myMap’,response. …
}); $A. enqueueAction(action);
