I am using this code to get the last day of the current month
getLastDayOfMonth() {
const date = new Date()
const month = date.getMonth() + 1
const year = date.getFullYear()
return new Date(year, month, 0).getDate()
}

Most of these answers are missing one thing or another. After playing with most of them I came up with the following that gives you the last possible millisecond of the month.
let testDate = new Date();
console.log(getMonthEnd(testDate));
function getMonthEnd(value) {
return new Date(value.getFullYear(), value.getMonth() + 1, 0, 23, 59, 59, 999);
}
Probably missing something in this one too but seems to cover all my requirements.

Last day of the month
now = new Date
lastDayOfTheMonth = new Date(1900+now.getYear(), now.getMonth()+1, 0)

Do not forget month started with 0 so +1 in month too.
let enddayofmonth = new Date(year, month, 0).getDate();

var d = new Date();
console.log(d);
d.setMonth(d.getMonth() + 1); // set month as next month
console.log(d);
d.setDate(0); // get the last day of previous month
console.log(d);
Here is output from the code above:
Thu Oct 03 2013 11:34:59 GMT+0100 (GMT Daylight Time)
Sun Nov 03 2013 11:34:59 GMT+0000 (GMT Standard Time)
Thu Oct 31 2013 11:34:59 GMT+0000 (GMT Standard Time)

function LastDayOfMonth(Year, Month) {
return new Date((new Date(Year, Month, 1)) - 1);
}
console.log(LastDayOfMonth(2009, 11))
Example:
> LastDayOfMonth(2009, 11)
Mon Nov 30 2009 23:59:59 GMT+0100 (CET)

Sometimes all you have is a text version of the current month, ie: April 2017.
//first and last of the current month
var current_month = "April 2017";
var arrMonth = current_month.split(" ");
var first_day = new Date(arrMonth[0] + " 1 " + arrMonth[1]);
//even though I already have the values, I'm using date functions to get year and month
//because month is zero-based
var last_day = new Date(first_day.getFullYear(), first_day.getMonth() + 1, 0, 23, 59, 59);
//use moment,js to format
var start = moment(first_day).format("YYYY-MM-DD");
var end = moment(last_day).format("YYYY-MM-DD");

var month = 1; // 1 for January
var d = new Date(2015, month, 0);
console.log(d); // last day in January

var d = new Date();
m = d.getMonth(); //current month
y = d.getFullYear(); //current year
alert(new Date(y,m,1)); //this is first day of current month
alert(new Date(y,m+1,0)); //this is last day of current month

Calendar cal = Calendar.getInstance();
cal.set(Calendar.DATE, cal.getActualMaximum(Calendar.DATE));
Date lastDayOfMonth = cal.getTime();

This will give you last day of current month.
var t= new Date();
alert(new Date(t.getFullYear(), t.getMonth() + 1, 0, 23, 59, 59));
