var temperatures = [100,90,99,80,70,65,30,10]; for(var i = 0; i <=6; i +=1){ console.log(temperatures[i]); }

in my Atom editor was right but here says wrong.

script.js 
var temperatures = [100,90,99,80,70,65,30,10];
for(var i = 0; i <=6; i +=1){
 console.log(temperatures[i]);
}

Hi Paulos,

I'd suggest using the array.length to avoid the miscount (also makes it easier with very large arrays).

Something like this perhaps:

var temperatures = [100,90,99,80,70,65,30,10];

for (var i = 0; i < temperatures.length; i++) {
  console.log(temperatures[i]);
}

Everything else looked fine though. Happy coding,

Dave.
