I am trying to do something like this
var teller = 1;
if (teller % 2 === 0) {
"do this"
} else {
"do something else"
}
teller++;
The problem is that he always comes into the else loop. Someone knows why?
because 1 % 2 === 0
returns false
you might want to put it inside a loop
var teller = 1;
while(teller < 100){ //100 is the range, just a sample
if (teller % 2 === 0) {
"do this"
} else {
"do something else"
}
teller++;
}
Stepping through your code:
var teller = 1; //teller is now 1
if (teller % 2 === 0) { //1 % 2 === 1, so this statement is skipped
"do this"
} else { //since the if statement was skipped, this gets run
"do something else"
}
teller++; //this has no affect on the above
If you want to put this in a loop, see @DryrandzFamador's answer.
