Assign Values of an Array to each value of another array and submit in a JSON format in typescript

Question

I have two arrays, one having user ids and another having tags. ''' ["ELG001", "ELG002"] ["TG01", "TG02"]

''' am supposed to submit to an endpoint that expects a json in this format ''' "id_tags": [{ "id": "ELG001", "tag": "TG01,TG02" }, { "id": "ELG002", "tag": "TG01,TG02" } ] '''

How can I achieve to send the data in the expected format using map function

I created a simple snippet for you below based on your question that you want the first array to be the id and just add the second array as tags for your json.

const idArray = ["ELG001", "ELG002"];
const tagArray = ["TG01", "TG02"];
let tagArr = [];
idArray.forEach((el) => {
  tagArr.push({
    id: el,
    tag: tagArray.join(",")
  })
})
const tag = {
  id_tags: tagArr
}
console.log(tag);

what if it is required in this format "id_tags": [{ "id": "ELG001", "tag": "TG01" }, { "id": "ELG001", "tag": "TG02" } { "id": "ELG002", "tag": "TG01" } { "id": "ELG002", "tag": "TG02" } ]

const idArray = ["ELG001", "ELG002"] // is supposed to be reporter Ids const tagArray = ["TG01", "TG02"] // is supposed to hold selected tags const tagArr = []; idArray.forEach((el) => { tagArray.forEach((ll) =>{ tagArr.push({reporter: el, tag: ll }) }) }) const reporterTags = { reporter_tags: tagArr } console.log(reporterTags);
