I'm able to get an external sites HTML code. Inside that code they have a javascript code which has a JS object called myListItems.

I know how to get the HTML via file_get_contents but how canI scrape the JS code so I can use it?

Essentially you can't. Javascript is client side so you cannot know what is happening when executed by the user/browser. You can pull the script itself depending on if it is embedded in the HTML or pulled from a file. You would have to analyze the <javascript> tag(s) to determine which. After that you would need to know what the user/browser actions are to execute it. Finally you would have to emulate its execution on the server using the same conditions as the user/browser. All of that is virtually impossible.
