for ( var counter = 5; counter; counter = counter -1) {
alert("Hello WOrld", counter);
}
This suppose to alert Hello world with counter at the end 10 times and every time counter gets - 1 .
But after i run this code this alerts hello world 10 times but doesn't display the counter
Any Help ?

takes only 1 argument. If you want to see counter
displayed use the following format:
alert("Hello World " + counter);
console.log()
, which is used in the video, does take comma separated objects to be output:
console.log("Hello World", counter);

for (var counter=5; counter; counter--) {
alert("Hello World " + counter);
}
