JByte is a JavaScript port of the C# function String.Format
JByte uses the same logic as C#'s String.Function
For example:
var firstName = "Tom";
var surName = "Davies";
document.write(JByte("My name is {0} {1}",firstName,surName));will write
My name is Tom Davies
At the moment, JByte is able to use up to 10 variables ( {0} - {9} )
