I'm trying to sort this array of objects by its boolean properties however, I'm struggling to find a solution with javascripts 'sort' method

I'm trying to sort it, so the top item in the array would be 'offer = true', then 'shortlisted = true', and finally 'rejected = true'.

var toSort = [{

    offer: false,

    shortlisted: true,

    rejected: false,

    stage: 2

}, {

    offer: false,

    shortlisted: false,

    rejected: true,

    stage: null

}, {

    offer: true,

    shortlisted: true,

    rejected: false,

    stage: null

}, {

    offer: false,

    shortlisted: true,

    rejected: false,

    stage: 1

}];

This is the final result I would like to achieve

[{

    offer: true,

    shortlisted: true,

    rejected: false,

    stage: null

}, {

    offer: false,

    shortlisted: true,

    rejected: false,

    stage: 1

}, {

    offer: false,

    shortlisted: true,

    rejected: false,

    stage: 2

}, {

    offer: false,

    shortlisted: false,

    rejected: true,

    stage: null

}]

What is the best method to sort this array?

You can use sort() like this.

var toSort = [{

  offer: false,

  shortlisted: true,

  rejected: false,

  stage: 2

}, {

  offer: false,

  shortlisted: false,

  rejected: true,

  stage: null

}, {

  offer: true,

  shortlisted: true,

  rejected: false,

  stage: null

}, {

  offer: false,

  shortlisted: true,

  rejected: false,

  stage: 1

}];



var result = toSort.sort(function(a, b) {

  return b.offer - a.offer ||

    b.shortlisted - a.shortlisted ||

    b.rejected - a.rejected

})



console.log(result)
