Merge two arrays matching an id

Question

I have two arrays like

var members = [{docId: \"1234\", userId: 222}, {docId: \"1235\", userId: 333}];
var memberInfo = [{id: 222, name: \"test1\"}, {id: 333         


        

Answer 1

function computeMembers(members, memberInfo) {
  return members.map(function(member) {
    member.name = memberInfo[getMemberById(member.userId, memberInfo)].name
    return member
  })

  function getMemberById(id, elements) {
    var index = elements.filter(function(element) {
      return element.id === id
    })[0]
    return elements.indexOf(index)
  }
}

console.log(computeMembers(members, memberInfo))
