Inside the module, create a js directory to hold the file(s) for the third-party JS code, in this example, it's called file.js. For the sake of the following examples, it's called myblock.

Sometimes, however, site builders and developers need to add functionality or create features that are not provided in Drupal core or a contributed module, but perhaps can be provided by a third-party JS library or file.
