loop list of objects with numbers [duplicate]

Question

I am looping over list of objects but when calling a async function I get array of objects with numbers and now i cannot map the arrays.

 { '0': { id: '22be325d3564d713', name: 'dasdasdas', affiliateIds: 2, platformIds: 2, campaignIds: [], deviceOses: [], deviceTypes: [], countryCodes: [], entryType: 'RED', model: 'REVENUE_RATIO', value: 0.01, active: 1, createdAt: 2020-06-11T06:00:53.000Z, updatedAt: 2020-06-11T06:00:53.000Z }, '1': { id: '2891e303645099fd', name: '', affiliateIds: [], platformIds: [], campaignIds: [], deviceOses: [], deviceTypes: [], countryCodes: [], entryType: 'CNV', model: 'REVENUE_RATIO', value: 0.7, active: 1, createdAt: 2018-01-09T11:12:29.000Z, updatedAt: 2018-01-09T11:12:29.000Z },

i am trying to get the ids using

Object.map(a => a.id);

but because of the numbers i cannot get the ids

The thing you posted is not (in JavaScript terms) a list; it's a plain object. — Pointy

You can use Object.values() if you are not interested in the numeric property names

const res = Object.values(data).map(({id}) => id) console.log(res)

<script> const data={0:{id:"22be325d3564d713",name:"dasdasdas",affiliateIds:2,platformIds:2,campaignIds:[],deviceOses:[],deviceTypes:[],countryCodes:[],entryType:"RED",model:"REVENUE_RATIO",value:.01,active:1,createdAt:"2020 - 06 - 11 T06: 00: 53.000 Z",updatedAt:"2020 - 06 - 11 T06: 00: 53.000 Z"},1:{id:"2891e303645099fd",name:"",affiliateIds:[],platformIds:[],campaignIds:[],deviceOses:[],deviceTypes:[],countryCodes:[],entryType:"CNV",model:"REVENUE_RATIO",value:.7,active:1,createdAt:"2018 - 01 - 09 T11: 12: 29.000 Z",updatedAt:"2018 - 01 - 09 T11: 12: 29.000 Z"}}; </script>
