SAPUI5: How to use external library in controller?

问题

In my index.html file I have the following code:

<script>
        sap.ui.getCore().attachInit(function() {
            jQuery.sap.registerModulePath("lodash","https://cdn.jsdelivr.net/npm/lodash@4.17.4/lodash.min");
        jQuery.sap.require("lodash");

        new sap.m.Shell({
            app: new sap.ui.core.ComponentContainer({
                height : "100%",
                name : "sap.com.ml.docservicedoc-service-m-learning"
            })
        }).placeAt("content");
    });

How can I now use lodash in one of my controllers (not view)? I tried:

sap.ui.define([
"sap/ui/core/mvc/Controller",
"lodash"], function(Controller, _) {

Unfortunately "_" is always undefined.

Figured out a solution:

1. Create libs folder in your project and put the library into that folder
2. Inside your controller add the library as the following. Also keep in mind that the value in the define function should be different to the global name of the library:

sap.ui.define([
       "sap/ui/core/mvc/Controller",
       "<project namespace>/libs/lodash/lodash.min",
   ], function(Controller, lodash) {

3. Use global root variable of library. In case of lodash it is "_"
