$.repeat(group, interval ,runNow ,callback)

Description: Begin a sequential loop that is triggered by a given interval for a named thread group.

group – string, optional
a name of the thread group that this loop should be assigned to.
Defaults to the empty string ''.
interval – number
the number of milliseconds between each trigger.
runNow – boolean, optional
whether to start the loop immediately for the first time.
Defaults to false.
callback – function(count…), optional
a method that is called once per loop iteration.
All current iteration counts (from inner-most to outer-most loop) are passed as arguments.

The static $.unrepeat() allows to break repeat-loops started this way.

Usage pattern

$.repeat(interval, function(){  });
