for loop statement 3

Question

using pre increment gave the result as the post increment
post increment i

for (i=1; i<=5; i++) {
document.write(i + "<br />");

pre increment i will give same results

for (i=1; i<=5; ++ i) {
document.write(i + "<br />");

Answer 1

That is because they differ where they are assigned to some variable...

x = y++ // y is assigned to x, then incremented
x = ++y // y is incremented then assigned to x.

However, when they are on a single line, they would act the same...

y++
x = y // y is incremented on first line and assigned on second

++y
x = y // y is incremented on first line and assifned on second.
