Javascript – Get specified element in array

I got have the output of [Document<Recording<string, any>>, number][]
each element is described as:

 [
    Document{
      page: 'I have worked for ABC company',
      meta: { id: emloyee-111, name: 'John"}
    },
    245
 ]
 [
    Document{
      page: 'I'm Software developer',
      meta: { id: emloyee-444, name: 'Marry"}
    },
    789
  ]

  For (employee of employees) {
     // get id
     // get name
     // get the number 245, 789
  }

In typescript (or javasSript), how to I get the numbers (245, 789) of two employees and their id and name.

    Just iterate over the output

    for (const [doc, num] of output) {
  const { id, name } = doc.employee;
  console.log({ id, name, num });
}

    Or, if you’re trying to get to the data from an employees array:

    for (const employee of employee) {
  const entry = output.find(([doc]) => doc.employee.id === employee.id);

  if (entry) {
    const [doc, num] = entry;
    const { id, name } = employee;
    console.log({ id, name, num });
  }
}

    You should supply your types and provide actual TypeScript code.

    The following structure should work:

    interface Recording {
  id: string;
  name: string;
}

interface EmployeeDocument {
  page: string;
  meta: Recording;
}

type Employee = [EmployeeDocument, number];

const employees: Employee[] = [
  [
    {
      page: "I have worked for ABC company",
      meta: { id: "emloyee-111", name: "John" },
    },
    245,
  ],
  [
    {
      page: "I'm Software developer",
      meta: { id: "emloyee-444", name: "Marry" },
    },
    789,
  ],
];

for (let employee of employees) {
  const [{ page, meta: { id, name } }, count ] = employee;
  console.log({ page, id, name, count });
}

    "use strict";

const employees = [
    [
        {
            page: "I have worked for ABC company",
            meta: { id: "emloyee-111", name: "John" },
        },
        245,
    ],
    [
        {
            page: "I'm Software developer",
            meta: { id: "emloyee-444", name: "Marry" },
        },
        789,
    ],
];

for (let employee of employees) {
    const [{ page, meta: { id, name } }, count] = employee;
    console.log({ page, id, name, count });
}
    .as-console-wrapper { top: 0; max-height: 100% !important; }

    Output

    {
  "page": "I have worked for ABC company",
  "id": "emloyee-111",
  "name": "John",
  "count": 245
}
{
  "page": "I'm Software developer",
  "id": "emloyee-444",
  "name": "Marry",
  "count": 789
}
