for loop logging to console syntax/parse error

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

let i = 0;

while( i < temperatures.length ) { console.log( temperatures[i] ); i+=1; }

the above code works in my browser and accomplishes the task to print it to the console. I Did I miss something in the instructions. Any help would be great!

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

let i = 0;

while( i < temperatures.length ) {
    console.log( temperatures[i] );
    i+=1;
}

Your original code works as well if you use var instead of let. The checker doesn't support let.

Maybe that was it. Will be sure to use ‘var’ in the future! Thx!

Use the shorthand increments i++;

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

var i = 0;

while( i < temperatures.length ) { console.log( temperatures[i] ); i++1; }

for some reason this worked!
