When you are doing a for loop you need to put a semicolon between declaration items. So in your case you would need to have the following:

```for(var i=0; i<temperatures.length; i+=1){

 console.log(temperatures[i]);

}```

Hey anuj,

It's a simple syntax error. Inside your for loop, you are using commas instead of semi-colons. Fix that up and you'll be good to go.

for(var i=0, i<temperatures.length, i+=1){

should be

for(var i=0; i<temperatures.length; i+=1){

Keep Coding! :)
