Code doesn't do what i expected it to do

Question

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 ?

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

Try this out. Javascript uses the + symbol to concatenate a string.  
javascript
for (var counter=5; counter; counter--) {
  alert("Hello World " + counter);
}
