Grouping & Group Counts

Example

Scenario;
You have a CMS collection of Locations, which each have a State. You want to show a list of States, with the count of Locations in each.
Let's suppose you have setup this SA5 Data source.
Once loaded, the data it will exist as a JavaScript Map in SA5's Datastore;
ds.store.locations.data
You can transform that Map into a new map which contains Groups and counts, like this;
// Get count of locations in each state
let result = new Map();
ds.store.locations.data.forEach(({ state }) => {
result.set(state, (result.get(state) || 0) + 1); // increment state count
});
Now you can use your result Map however you like.
