Description

You can use delay if you want to wait a specific amount of time before running code. This function can be used in combination with other shinyjs functions, such as hiding or resetting an element in a few seconds, but it can also be used with any code as long as it's used inside a Shiny app.

delay(ms, expr)

The number of milliseconds to wait (1000 milliseconds = 1 second) before running the expression.
