# m

Map utilities for Go

### `Get` and `Set` using JavaScript notation

Before (yeah it scrolls):

```

// set the city

data.(map[string]interface{})["addresses"].([]interface{})[0].(map[string]interface{})["city"] = "London"

// get the city

city := data.(map[string]interface{})["addresses"].([]interface{})[0].(map[string]interface{})["city"]

```

  * Panics if any piece is missing or wrong type

After:

```

m.Set(data, "addresses[0].city", "London")

city := m.Get(data, "addresses[0].city")

```

  * Returns nil if any piece is missing or wrong type

  * Use [`GetOK`](http://godoc.org/github.com/matryer/m#GetOK) for a second argument bool
