Date number javascript -

i'd make smart name in our automation engine javascript show last number of year , current week's number. this: 520

function f () { var today = new date(); var weekno = today.getweek(); return weekno; } f ();

this co-worker's try. idea?

get week

 var today = new date();  var weekno = today.getweek();

get year

 var weekno = new date().getfullyear()

subtring value that

var str = "hello world!"; var res = str.substring(1, 4);

and combine both that

var str1 = "hello "; var str2 = "world!"; var res = str1.concat(str2);
