Both of the above would be considered initialization IMHO. Either way, you're better off from a performance standpoint to not initialize the variable until you use it, since if the code never gets to the initialization then you'll have saved some processing time. That said, if most of my vars are going to be used I generally like to initialize them all at the top of the function for better readability.
