Perform common useful JavaScript operations in Shiny apps that will
greatly improve your apps without having to know any JavaScript.
Examples include: hiding an element, disabling an input, resetting an
input back to its original value, delaying code execution by a few
seconds, and many more useful functions for both the end user and the
developer. 'shinyjs' can also be used to easily call your own custom
JavaScript functions from R.
