To the author, here's a common pattern you can use to avoid defining global variables unless it's needed.

  ;(function() {
    const dropzoneDefaults = { ... }
    class EasyDropzone { ... }
    const h = function() { ... }

    // Export to global
    window.EasyDropzone = EasyDropzone
  })()

Thanks. Will definitely try to improve the code. JavaScript is not my main language and I still have many tricks that I should learn.

Here is some information about this pattern, it's called Immediately Invoked Function Expression. It's a way to create a function scope so that all variables are local, except for any that you want to "export" as a global.
