what is the use of ' text"" ' and 'text i'

Question

what is the use of ' text"" ' and 'text i' in the given code:-
for (i=1, text=""; i<=5; i++) {
text = i;
document.write(i + "<br />");
}

Answer 1

In my opinion there is no use, unless I am missing something or your code snippet is missing some context. The iteration variable i is being assigned to text, but not used. Omitting the text in the loop declaration and loop execution gives the same output.
