`#element` + document undefined

[orpheus]

This may be a dumb question, but what is #element ? What is its purpose or function?

How would I go about using the following in React? Just throw it in a div?

init(`#element`, {
  // required - for now, only accepting texts
    strings: ['Dead simple animated typing.', 'No dependencies'],
    //optional

Also, when I try to paste in the example code, I get ReferenceError: document is not defined
