How does uglify work in webpack?

Question

JavaScript

Good day.
Tell me how the import/export of code between modules works in ugly webpack.
And more precisely, this piece is interested in how to navigate by the numbers 1, 2, 3:

webpackJsonp([1], [
    function (e, t, n) {
        var a = n(1), b = n(2), c = n(3);
    }
], [3]);

PS There are no sources :). I would be very grateful for the saved time.

Answer 1

Numbers are numbers :-)
This closure calls the function passed as the third argument three times. The first time with parameter 1, the second time with 2, the third time with 3. The first and second arguments are not used.
