why this code doesn't work ?

I create for loop with condition i=0. I made the condition runs through the length of the variable and calls it in the console.log. I can't figure out what I did wrong :(

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

You have a syntax error, you write "lenght" instead of "length" in the for loop.
