Change a numeric value into a string within a collection of objects

Consider the following input array:

  const initialArray = [
    {
      id: 1,
      name: 1
    },
    {
      id: 2,
      name: 2
    },
    {
      id: 3,
      name: 3
    },
    {
      id: 4,
      name: 4
    }
  ];

The objective is to modify it to:

  updatedArray = [
    {
      id: 1,
      name: '1'
    },
    {
      id: 2,
      name: '2'
    },
    {
      id: 3,
      name: '3'
    },
    {
      id: 4,
      name: '4'
    }
  ];

to convert the value of 'name' to a string. A potential solution involves using the map method but you feel that it may be too complex:

  const updatedArray = initialArray.map((element) => ({
    ...element,
    name: element.name.toString()
  }));

Are there any simpler alternatives to achieve this transformation?

Answer №1

Utilizing destructuring along with utilizing the String function.

Make a comparison between using toString and String by visiting this link: What are the variances between String(value) vs value.toString()

const input = [
  {
    id: 1,
    name: 1,
  },
  {
    id: 2,
    name: 2,
  },
  {
    id: 3,
    name: 3,
  },
  {
    id: 4,
    name: 4,
  },
];

const output = input.map(({ name, ...rest }) => ({
  ...rest,
  name: String(name),
}));

console.log(output)

Answer №2

Your proposed solution is solid and I believe it is the most optimal one available. In addition to the mentioned solution, you can also consider this alternative based on your specific needs:

input.forEach(element => element.name = element.name.toString());

With this approach, the objects themselves will be altered rather than generating fresh copies.
