copy code in html file and paste it into javascript file

I'm trying to get entire html file content and paste it inside the JavaScript file.

for example, I have a html file like this: hello.html

<div>
   <a>hello world</a>
</div>

and in js file I want to paste that html content. so it looks like this: hello.js

//pasted html file
   <div>
       <a>hello world</a>
    </div>

is their method or function that can do similar job like that?
