## README

Counting Map

A basic map that keeps count of each unique item you set and cleans up only when all counters have been deleted.


Examples:
```
 const counter = new CountingMap();
 counter.set('key', 'value');
```

Adding and removing:
```
    counter.set('key', 'value');
    counter.set('key', 'value');
    counter.delete('key');
```
This example will keep one instance of key in the map
If we run another delete:
```
    counter.delete('key');
```
no items with key 'key' are in the map

Only updating with no incrementing:
```
    const counter = new CountingMap();
    counter.set('key', 'value');
    counter.update('key', 'value1');
```
