`window.prompt` opens a confirmation dialog with an "Ok"
and "Cancel" button. Upon receiving input, the dialog is
closed and a boolean is returned. `window.prompt` returns
the input string if the "Ok" button was pressed or null
if "Cancel" was pressed.

Note that this will pause code execution until
the dialog receives input. You can't fully get
around this, however using asynchronous
functions or promises, you can get other
statements to be called just after the dialog
is closed and before the dialog returns its
response.
