Which of the following is a favor? I want to change the PHP function to a JS function. thank you!

Which one is helpful? modify the PHP function to a JS function. thank you! Functionbmrs ($ weight = 0, $ sex = 1, $ age) {switch ($ age) {case $ age & gt; = 0and $ age & lt; 3: $ x = ar: which one is helpful? Change the PHP function to a JS function. thank you!
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); // round the floating point number

}

Which of the following are built-in parameters? are the first two default values? $ Weight = 0, $ sex = 1, $ age

These two codes are modified to JS, and the difficulty is:

Case $ age> = 0 and $ age <3:
$ X = array (1 => array (60.9,-54), 2 => array (61.0,-51 ));


Which of the following is a favor? change it to JavaScript. thank you.



------ Solution --------------------

JScript code

function bmrs(weight,sex,age){    var x=new Array(2),y=null;    switch (true)    {        case age>=0 && age<3:            x[1]=new Array(60.9,-54),x[2]=new Array(61.0,-51);            y=1;            break;        case age>=3 && age<10:            x[1]=new Array(22.7,495),x[2]=new Array(22.5,499);            y=1;            break;        case age>=10 && age<18:            x[1]=new Array(17.5,651),x[2]=new Array(12.2,746);            y=1;            break;        case age>=10 && age<18:            x[1]=new Array(17.5,651),x[2]=new Array(12.2,746);            y=0.95;            break;        case age>=18 && age<30:            x[1]=new Array(15.3,679),x[2]=new Array(14.7,496);            y=0.95;            break;        case age>=30 && age<60:            x[1]=new Array(11.6,879),x[2]=new Array(8.7,829);            y=0.95;            break;        case age>=60:            x[1]=new Array(13.5,487),x[2]=new Array(10.5,596);            y=0.95;            break;        default:           break;    }    return Math.ceil((x[1][0]*weight+x[1][1])*y); }
