10,406 Pointswhy does my code say 'Strict mode forbids implicit creation of global property 'i''?
i used a for loop but it came back with this and i dont know why
//console.log(2);
//console.log(4);
//console.log(6);
//console.log(8);
//console.log(10);
//console.log(12);
//console.log(14);
//console.log(16);
//console.log(18);
//console.log(20);
//console.log(22);
//console.log(24);
var even = 0;
for (i = 0; i < 13; i++) {
even += 2;
console.log(even);
}

What is likely happening here is that Treehouse's workspace codebase is applying strict mode which will require you to use the appropriate 'var i' syntax in your for loop. Hope this helps...

Front End Web Development Techdegree Student 13,532 PointsI had the same thing but i fixed by reading what you said, thanks!
const temperatures = [100, 90, 99, 80, 70, 65, 30, 10];
for (var i = 0; i < temperatures.length; i++) {
console.log(temperatures[i]);
}
