Answer 1

var currentday = new Date();
var nextDay = new Date();
nextDay.setDate(currentday.getDate() + 4);

Answer 2

//Set number of days you want to compute to
var days=4;

//Get current date or whatever date you want to compute from
var currentDate=new Date();

var nDaysFromNow=new Date();
nDaysFromNow.setDate(currentDate.getDate()+days);

Answer 3

You can add days using the getDate() function like so:

var someDate = new Date();
someDate = someDate.getDate() + 3;

Answer 4

See code below.. Hope it helps

var days = 4;
var next = new Date((new Date).getTime() +  ((1000*3600*24) *days));
