An array of objects of same structure is given. Each object contains a property `label` besides other properties. Same labels are equal accross the objects. The goal is to group the objects by the labels.

Group by label property

// Get an array of all labels with unique entries.
const uniqueLabels = [...new Set(apps.map(item => item.label))];

// Transform the original array of objects to an array of label groups.
const groupedApps = uniqueLabels.map(label => ({ label, stores: apps.filter(app => app.label.includes(label)) }));
