Answer 1

✩✮★✮✩ thanks it worked,
but i dont understand, since 'i' is within functions and not declared outside they should be local? or is it that i passed 'i' as argument to another function with 'i' variable?

Answer 2

~LoneWolf

There are loops in to function like
function isprime(n)
function allprimes(n)

allprimes (n) function calls
isprime (n) function

Both has for loop in those function share common global variable I

That makes code giving clumsy output as both function manipulate global variable i

so for loop needs to be written like
for (var i = 2; I < num; I++)

instead of
for (I = 2; I < num; I++)

It will fix the code

DHANANJAY PATEL thanks i am going to use "var" everytime now when declaring 'i' within loop. or shall i use "let" whats the difference between both?

Answer 4

✩✮★✮✩ thanks, so i guess "let" suits better for loops.
