by mapping, I also require to get data from another api endpoint for each of the elements of state.trainData
.
I am using a helper function to fetch me data but thats where i hit a roadblock. I do get the data fine but the problem is I can not get it out on a variable or so to place it in a component.
In the render function after the call of getSpecificTrainDetails

We're going to want to "chain" these promises to achieve the desired effect. This mostly involves returning the promises created inside of another promise callback. We'll also have to introduce the $q
dependency so we can resolve multiple promises concurrently.
