Can you give an example?

[Will-Sommers]

loggingClient = {
  loggingFnOne: function (args){....},
  loggingFnTwo: function (args){....}
}

var doSomeWork = function(args) {
  logFn = args.predicate ? "loggingFnOne" : "LoggingFnTwo";
  loggingClient[logFn](args);
}

Sort of contrived example but it is a pretty O_o moment for some folks.
