How to convert an array of string into a Javascript object?-CodePudding

Each user's information is separated by a comma, or a space, but some pieces of information can be blank. I'm looking for a solution to take the user information and create an object (key-value mapping). Here's my approach, but I can't get multiple objects.

function Person(name, email, age, occupation) {
  this.name = name;
  this.email = email;
  this.age = age;
  this.occupation = occupation;
}

let string = "Norbert,[email protected],51,Coder Noemi,,,Teacher Rachel,[email protected],,"
let stringArr = string.split(/[\s,] /)

const personObj = new Person(...stringArr)

console.log(personObj)

When splitting the string, you need to keep the empty strings between the commas, but you are splitting sequences of commas as one divider - [\s,] .

Split the string by a single , or a sequence of spaces - /,|\s /. Then create an array of Person using Array.from(), dividing the original length by 4, and taking 4 properties by slicing the original array:

function Person(name, email, age, occupation) {
  this.name = name;
  this.email = email;
  this.age = age;
  this.occupation = occupation;
}

const string = "Norbert,[email protected],51,Coder Noemi,,,Teacher Rachel,[email protected],,"
const stringArr = string.split(/,|\s /)

const personArr = Array.from({ length: stringArr.length / 4 }, (_,i) => 
  new Person(...stringArr.slice(i * 4, i * 4   4))
)

console.log(personArr)

Assuming space is a line separator, and comma is a field separator, split:

function Person(name, email, age, occupation) {
  this.name = name;
  this.email = email;
  this.age = age;
  this.occupation = occupation;
}

let string = "Norbert,[email protected],51,Coder Noemi,,,Teacher Rachel,[email protected],,";

const persons = string.split(' ').map(r => new Person(...r.split(',')));

console.log(persons)
