Example: Overview of functions

const s = Sets.mutable();
s.add(item);    // Add one or more items. Items with same key are overriden.
s.has(item);    // Returns true if item value is present
s.clear();      // Remove everything
s.delete(item); // Delete item by value
s.toArray();    // Returns values as an array
s.values();     // Returns an iterator over values
s.size;         // Number of items stored in set

Example: Example usage

// Data to add
const people = [
 {name: `Barry`, city: `London`}
 {name: `Sally`, city: `Bristol`}
];

// Create a set, defining how keys will be generated
const set = Sets.mutable(person => {
   // Key person objects by name and city.
   // ie. Generated keys will be: `Barry-London`, `Sally-Bristol`
   return `${person.name}-${person.city}`
});

// Add list
set.add(...people);

// Demo:
set.has({name:`Barry`, city:`Manchester`})); // False, key is different (Barry-Manchester)
set.has({name:`Barry`, city:`London`}));     // True, we have Barry-London as a key
set.has(people[1]);   // True, key of object is found (Sally-Bristol)
