Webpack, json, jquery?

.the js file starts with

webpackJsonp([31, 1, 23, 28, 66], [function(e, t) {
 e.exports = jQuery
},

e.exports = {
 init: function() {
 this.cache(), this.initResize();
},
 cache: function() {
...
},
 initResize: function() {
...
}
}
}).call(t, n(0))

How does it work ? How to achieve such a result or where can I see info on this ?
