跪求！js 不知名用法 无法理解感激不尽

Question

webpackJsonp([1],{0:function(e,t,o){o("j1ja"),e.exports=o("NHnr")},AEiS:function(e,t){},Due5:function(e,t){},"G/Qq":function(e,t){},NHnr:function(e,t,o){"usestrict";Object.defineProperty(t,"__esModule",{value:!0});}}请问o("NHnr")这是什么用法？vara=o("//Fk"),i=o.n(a),n=o("7+uW")这种形式怎么理解，看的一脸懵逼
