import reduce from 'just-reduce-object';
// applies a function against an accumulator and each key-value pairs of the object
// to reduce it to a single value
reduce({a: 3, b: 5, c: 9}, (acc, key, value, index, keys) => {
acc[value] = key;
return acc;
}, {}); // {3: 'a', 5: 'b', 9: 'c'}
reduce({a: 3, b: 5, c: 9}, (acc, key, value, index, keys) => {
acc += value;
return acc;
}); // 17
