use existing variable in for loop

Question

Is it possible to leave out the variable assignment from a for loop and do something like this…?

otherVar = 3;

for ( otherVar > 0; otherVar-- )
{
    stuff
}

Answer 1

Yes, but you need to put in the semi-colon:

var otherVar = 3;

for ( ; otherVar > 0; otherVar-- ) {
    doStuff();
}
