I also have this kind of problem, but for most time I simply take away the
"var" and then ignore it. This seems a good chance to make it clear.

Would you tell my why "var x=5" won't do it? To my understanding "initialize
an variable with something" is the same as "declaring the variable, then
assign its value with something".

Thank a lot. :)
