哪个帮个忙，把PHP函数修改为JS函数，谢谢！
function bmrs($weight=0,$sex=1,$age){
switch ($age) {
case $age>=0 and $age<3:
$x=array(1=>array(60.9,-54),2=>array(61.0,-51));
$y=1;
break;
case $age>=3 and $age<10:
$x=array(1=>array(22.7,495),2=>array(22.5,499));
$y=1;
break;
case $age>=10 and $age<18:
$x=array(1=>array(17.5,651),2=>array(12.2,746));
$y=1;
break;
case $age>=10 and $age<18:
$x=array(1=>array(17.5,651),2=>array(12.2,746));
$y=0.95;
break;
case $age>=18 and $age<30:
$x=array(1=>array(15.3,679),2=>array(14.7,496));
$y=0.95;
break;
case $age>=30 and $age<60:
$x=array(1=>array(11.6,879),2=>array(8.7,829));
$y=0.95;
break;
case $age>=60:
$x=array(1=>array(13.5,487),2=>array(10.5,596));
$y=0.95;
break;
default:
break;
}
return ceil(($x[$sex][0]*$weight+$x[$sex][1])*$y); //对浮点数进行四舍五入
}
自带参数这几个，前面二个是默认值吗？$weight=0,$sex=1,$age
这二个代码，修改为JS，遇到了难度：
case $age>=0 and $age<3:
$x=array(1=>array(60.9,-54),2=>array(61.0,-51));
哪位帮个忙，把它修改为JavaScript的，谢谢。
