Il est toujours amusant de jouer avec un chronomètre - même en JavaScript! Ce chronomètre ne comprennent même les caractéristiques de base de Start, Stop, et, bien sûr, Reset. Par ailleurs, le temps n'est pas régulier seconde lecture que vous avez probablement l'habitude. Il affiche en millisecondes! Par conséquent, 1000 = 1 sec, 5000 = 5 sec, etc ..
