==

`npm install ettr`

usage

==

Assume `obj` is

```js

{

  a: {

    b: {

      c: 1,

      d: 2,

    }

  }

}

```

### .get(obj, attr)

```js

ettr.get(obj, 'a.b.c')

  .should.equal(1);

ettr.get(obj, 'a[b]["c"]')

  .should.equal(1);

```

### .set(obj, attr, value)

```js

ettr.set(obj, 'a.b.c', 5);

obj.a.b.c.should.equal(5);

```

### .incr(obj, attr, value, defaultValue)

```js

ettr.incr(obj, 'a.b.z', 1, 100);

ettr.incr(obj, 'a.b.z', 1, 100);

obj.a.b.z.should.equal(102);

```

benchmark

==

see `benchmark.js`

```

#ettr x 800,747 ops/sec ±2.25% (93 runs sampled)

#eval x 2,918,739 ops/sec ±2.65% (87 runs sampled)

Fastest is #eval
