multibranch if or switch statement in coffeescript

I'm a little unsure of how to do this in coffeescript. Right now we have some code that sets a variable conditionally:

myCar.sparkPlug= options.sparkPlug if options.sparkPlug?

However, it's now possible the sparkPlug property may be initialized with another value:

myCar.sparkPlug = options.glowPlug if options.glowPlug?

What I want to do is set myCar.sparkPlug to the value of options.SparkPlug, but if options.glowPlug exists, use that. (It's possible the options object will have both a sparkPlug and glowPlug property.)

I can do it by listing the two lines of code above in order, but is there a more elegant way to do it?

If I understand, this is what You need:

myCar.sparkPlug = if options.glowPlug? then options.glowPlug else options.SparkPlug

or more complex:

myCar.sparkPlug = if options.glowPlug? then options.glowPlug else (if options.SparkPlug? then options.SparkPlug)
