and-killer

a better way to get obj's prop without eggache(蛋疼).

##effect

if you have to do:

var movieName = res && res.body && res.body.data && res.body.data.movieName;

you can:

var ak = require('and-killer');
var movieName = ak(res)('body.data.movieName');

when a prop is undefined, you will get:

false
