I need to implement a functionality in javascript which takes from week and to week as inputs i.e it takes week number of current month (ex : 1,2,3,4,5,6) and get the start date of the week and end day of other week in current month and current year

Ex: selecting 3 and 4 should give current month 3rd week first day and 4th week last day
In Nov:2018 output should be as 11/11/2018 and 24/11/2018

You can try below approach to figure out your expected result. Solution below takes month as an input so that we can verify for any month

function getDates(m, a, b) {

  var date = new Date()

  , y = date.getFullYear()

  , lastDate = new Date(y, m, 0).getDate()

  

  var offset = new Date(new Date().setDate(1)).getDay()

  

  return [(a - 1) * 7 + 1, b * 7].map(d => {

    d -= offset

    if(d < 1) d = 1

    if(d > lastDate) d = lastDate

    return d + '/' + m + '/' + y

  })

}



console.log(getDates(11,1,2))

console.log(getDates(11,2,3))

console.log(getDates(11,3,4))

console.log(getDates(11,1,5))

function getRange(week1, week2){

    var start = (moment().startOf('month') >  moment().startOf('month').add(week1 - 1, 'week').startOf('week')) ? moment().startOf('month') : moment().startOf('month').add(week1 - 1, 'week').startOf('week');

    var end   = ( moment().endOf('month')  <  moment().startOf('month').add(week2 - 1 , 'week').endOf('week')) ? moment().endOf('month'): moment().startOf('month').add(week2 - 1 , 'week').endOf('week');



    console.log(start.format('D/MM/YYYY'))

    console.log(end.format('D/MM/YYYY'))



}

If you can use moment.js
