How to sort array of objects by its boolean properties

Question

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?

Answer 1

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)
