Uncaught ReferenceError: H is not defined

As your guide, I tried to inject css and js libs into page using below code.

`var styleSheet = document.createElement('link');
styleSheet.href = 'https://js.api.here.com/v3/3.0/mapsjs-ui.css?dp-version=1549984893';
styleSheet.type = 'text/css';
document.getElementsByTagName('head')[0].appendChild(styleSheet);

const javaScriptLibs = [
"https://js.api.here.com/v3/3.0/mapsjs-mapevents.js",
"https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js",
"https://js.api.here.com/v3/3.0/mapsjs-core.js",
"https://js.api.here.com/v3/3.0/mapsjs-service.js",
"https://js.api.here.com/v3/3.0/mapsjs-ui.js",
];

javaScriptLibs.forEach(x => {
var script = document.createElement('script');
script.src = x;
script.type = 'text/javascript';
document.getElementsByTagName('head')[0].appendChild(script);
});`

Right after these js libs are injected, I got the errors as below:
Can you help me please?

mapsjs-mapevents.js:1 Uncaught ReferenceError: H is not defined at mapsjs-mapevents.js:1
(anonymous) @ mapsjs-mapevents.js:1

mapsjs-ui.js:1 Uncaught ReferenceError: H is not defined at mapsjs-ui.js:1
(anonymous) @ mapsjs-ui.js:1

Oh I see the problem. It seems that the js lib some how will execute the code right after injected by above code. But when they are embedded using <script> tag in index.html, they won't execute.
