Separate text from a javascript array

  • 772

I have a arraywith idand descriptionwhere you have 2 roles , Owner and Tenant , I was trying to separate the role from each descriptionand add it to a arraynew one with its idcorresponding, something like:

{
  id: 1,
  description: "Propietario"
},
{
  id: 2,
  description: "Arrendatario"
}


I have the following code:

var rent = "Arrendatario";
var owner = "Propietario";
var obj = [{
    id: 1,
    description: "1664 - Propietario"
  },
  {
    id: 2,
    description: "1637 - Arrendatario - Finalizado"
  },
  {
    id: 3,
    description: "1735 - Arrendatario"
  },
  {
    id: 4,
    description: "LA6780 - Arrendatario"
  },
  {
    id: 5,
    description: "1638 - Arrendatario - Finalizado"
  }
];
console.log(obj);

The problem is that I need to separate the word Tenant or Owner from the String something with split()

javascript

    To perform the task you just have to go through the arrayand add elements to the new one arrayaccording to whether the value of the attribute descriptioncontains Arrendatarioor Propietario.

    const rent = "Arrendatario";
const owner = "Propietario";
const obj = [{
    id: 1,
    description: "1664 - Propietario"
  },
  {
    id: 2,
    description: "1637 - Arrendatario - Finalizado"
  },
  {
    id: 3,
    description: "1735 - Arrendatario"
  },
  {
    id: 4,
    description: "LA6780 - Arrendatario"
  },
  {
    id: 5,
    description: "1638 - Arrendatario - Finalizado"
  }
];
let newArray = [];
obj.forEach((document) => {
  let desc = '';
  let id = document.id;
  if (document.description.indexOf(rent) > -1) {
    desc = rent;
  }
  if (document.description.indexOf(owner) > -1) {
    desc = owner;
  }
  newArray.push({
    id: id,
    description: desc
  });
});
console.log(newArray);

    As you can see the code is pretty self explanatory. The value of each attribute is checked and arraywhat you want is stored in the new one.

    I hope it is what you were looking for.

  2. You can solve it with a map and includes:

    const rent = "Arrendatario";
const owner = "Propietario";
const obj = [
  {
    id: 1,
    description: "1664 - Propietario"
  },
  {
    id: 2,
    description: "1637 - Arrendatario - Finalizado"
  },
  {
    id: 3,
    description: "1735 - Arrendatario"
  },
  {
    id: 4,
    description: "LA6780 - Arrendatario"
  },
  {
    id: 5,
    description: "1638 - Arrendatario - Finalizado"
  }
];


const nuevoArray = obj.map(item => 
  item.description.includes(rent) ? 
   {...item,  description: rent} :
   {...item,  description: owner}
);

console.log(nuevoArray);
