Write a string followed by array items as a list

November 29, 2022

I have an array of objects, I want to be able to join it a string followed by having some of those array objects as part of a newly formed ordered list.

My code:

let arr = [
            {
              'message': "message 1",
              'date': "date 1",
              'text': "text 1"
            },
            {
              'message': "message 2",
              'date': "date 2",
              'text': "text 2"
            },
            {
              'message': "message 3",
              'date': "date 3",
              'text': "text 3"
            },
          ];
let new_arr = [];

arr.forEach(d => {
  new_arr.push(`The following messages: ${d.message} at ${d.date}`);
});

console.log(new_arr);

Is there any way I can get the code to do something like this:

The following messages:
    1. message 1 at date 1
    2. message 2 at date 2
    3. message 3 at date 3

>Solution :

like this?

let arr = [{
    'message': "message 1",
    'date': "date 1",
    'text': "text 1"
  },
  {
    'message': "message 2",
    'date': "date 2",
    'text': "text 2"
  },
  {
    'message': "message 3",
    'date': "date 3",
    'text': "text 3"
  },
];
let result_string = "The following messages:\n\t";
result_string += arr.map((a, i) => `${i+1}. ${a.message} at ${a.date}`).join("\n\t");
console.log(result_string);
