About this for loop please help me understand

Question

in this example "text" is useless because it's never printed on a page or console right? So what does text do?
for (i=1, text=""; i<=5; i++) {
text = i;
document.write(i + "<br />");
}

Answer 1

If "text" appears only in the code you displayed, you can remove it because it
will not affect the code.
