You are meant to round the temperature variable. So your code should look like this:

var temperature = 37.5;
alert(Math.round(temperature));

Hiya Shihab! The challenge needs ya to "round" the "temperature" to nearest value. And you already "temperature" defined the challenge editor, so yeah "temperature" variable instead of "39". Here is the code for your reference:

var temperature = 37.5;
alert(Math.round(temperature));
