BBQ thermometer, need help with code SyntaxError Unexpected token ;

Projects Programming

Hello everyone,
I've been playong with arduino a few times and now i want to do my first 'project'
I want to build a bbq thermometer.
I followed the guide here : https://www.safaribooksonline.com/blog/2013/07/25/an-arduino-powered-bbq-thermometer/#comment-157485

The code isn't clear and is divised in 3 section and i'm not sure exactly what goes where.

Here is my code :

var j5 = require("johnny-five");
var board = new j5.Board();

var LEDPIN = 13;
var THMPIN = "A0";

board.on("ready", function(){
  var led = new j5.Led(LEDPIN);
  var thm = new j5.Sensor({ pin: THMPIN, freq: 500 });

  var alertTemperatureF = 80;
  var currentTemp;

  thm.on("change",  function(err, thmVoltage){
    currentTemp = convertVoltToTemp(thmVoltage);

    if (currentTemp.tempF >= alertTemperatureF) {
      led.on();
    } else {
      led.off();
    }

    console.log("Current TempF: ", currentTemp.tempF);
  });

});

    // do stuff w/ the temperature, here
function convertVoltToTemp(volt){
  var tempK, tempC, tempF;

  // get the Kelvin temperature
  tempK = Math.log(((10240000/volt) - 10000));
  tempK = 1 / (0.001129148 + (0.000234125 * tempK) + (0.0000000876741 * 
      tempK * tempK * tempK));

  // convert to Celsius and round to 1 decimal place
  tempC = tempK - 273.15;
  tempC = Math.round(tempC*10)/10;

  // get the Fahrenheit temperature, rounded
  tempF = (tempC * 1.8) + 32;
  tempF = Math.round(tempF*10)/10;

  // return all three temperature scales
  return {
    tempK: tempK,
    tempC: tempC,
    tempF: tempF
  };
}
  });

});

here is the error i get when trying to run the code :
C:\Users\Garie\Desktop\Code arduino>node test.js

i'm using an arduino uno
Someone could help please?
Thank you

I don't know what IDE you are using, but we don't do much java here, just the C++.

That code does not look like C, C++, or Java. Perhaps it is javascript or python?

The Arduino IDE expects C andC++. Anything else is likely to lead to problems.

The text > is likely to cause problems in any programming language. This code has not been copied well.

Finally found a better way to do it.
