I have the following array of objects which also contains objects, available to me seen in the console as:

Array(2)
0 {GK: {job_numbers: ["56764"]}}
1 {AK: {job_numbers: ["12345", "5678", "78909"]}, MATT: {job_numbers: ["12345"]}}

Now I want to loop through this array in such a manor that I go to each object, and then also loop the elements inside.

For example,

I want to loop the array and get GK and its job numbers, then also get AK and its job numbers as well as MATT and its job numbers.

    please share expected output and code which you have tried so far – Naga Sai A May 14 '19 at 14:54

  • What have you tried? Did you even set up a loop? – Scott Marcus May 14 '19 at 14:55
  • I don't think that data structure is correct, if the 'GK' or 'MATT' supposed to be names, your nested object should look something like this: {name: 'MATT', job_numbers: [...]}, otherwise you have to explicitly use property names – alexlz May 14 '19 at 15:02

You can display each key and value by looping over each item in the array, then over the keys in each of the items:

const arr = [{GK: {job_numbers: ["56764"]}},{AK: {job_numbers: ["12345", "5678", "78909"]}, MATT: {job_numbers: ["12345"]}}]

for(var i in arr) {
    const obj = arr[i];
    Object.keys(obj).forEach((job, index) => {
        console.log(`${job}: ${obj[job].job_numbers}`)
    })
}

try

d.flatMap(o=> Object.keys(o).map(k=> `${k}: ${o[k].job_numbers}`));


let d=[{GK: {job_numbers: ["56764"]}}, {AK: {job_numbers: ["12345", "5678", "78909"]}, MATT: {job_numbers: ["12345"]}}
]

let r = d.flatMap(o=> Object.keys(o).map(k=> `${k}: ${o[k].job_numbers}`));

console.log(r);
