JMeter "if controller" with parameters?

I was reading the JMeter documentation and came across this info box about "If Controllers":

No variables are made available to the script when the condition is interpreted as Javascript. If you need access to such variables, then select "Interpret Condition as Variable Expression?" and use a __javaScript() function call. You can then use the objects "vars", "log", "ctx" etc. in the script.

I don't quite follow this. Does this mean if I want access to a "User Defined Parameter" then I can access it only by writing some JavaScript? The example that follows this box then refers to "${COUNT}"

Could someone clarify the usage of the If Controller, maybe with an example or two?

All these answers are wrong! You need to put the variable reference in quotes, like so:

"${my_variable}"=="foo"
