My first program in javascript...

Recently we studied the wet bulb temperature concept (wet bulb temperature for isobaric and adiabatic process). And in order to calculate it I created a simple javascript program. This is actually my first programm in javascript. The method is a simple Newton's method (http://en.wikipedia.org/wiki/Newton%27s_method). Check it out, if you are interested http://people.sca.uqam.ca/~huziy/WetBulbTemperature/main.html.
