Counter as an argument instead of a concatenation.

The is the example Jim typed:

for (var counter = 10; counter; counter = counter -1){ console.log("Hello world " , counter); }

Why did he type counter as an argument instead of concatenating counter?

Is there any significant difference or is this simply two ways of writing the same code. In chrome when counter is as argument the console highlights the numbers blue. When you concatenate counter the number is black like the hello world text.

looks like .log function has multiple forms

the first is .log(var)

the second is .log(var, var)

why did he type it the second way instead of using +, probably because it's faster
