Generating specific output based on the provided input parameter in JavaScript

Question

Generating specific output based on the provided input parameter in JavaScript

I have encountered a problem where I am able to get the output, but I am struggling to figure out how to change certain elements. Specifically, I have the total salary but I am unsure how to modify the keys and achieve the desired format.

The desired output format is as follows:

{
    "433": {
        employee_name: 'Rishi',
        total_salary: 5200
  },
    "434": {
        employee_name: 'pathak',
        total_salary: 5600 
  },
    "435": {
        employee_name: 'partap',
        total_salary: 5700
      }
  }

function takeInput(output){
            let total = [];
            let totalSalary = [];
            for(let i=0; i< output.length; i++){
                if(typeof(output[i].employee_data.salary[0]) == "object"){
                    total[i] = output[i].employee_data.salary[0];  
                    totalSalary[i] = addSalary(total[i]);
                    output[i].employee_data.salary[0]  = addSalary(total[i]);
                    console.log(output[i]);  
                }
            }
        }
        
        function addSalary(income){
            let total = 0;
            let values = Object.values(income)
            for(let i=0; i< values.length; i++){
              total = total + values[i];
            }
            return total;
        }
        
        
        
        let output = [
            {
              employee_data: {
                  employee_name: 'Rishi',

              }
            },
            {
                employee_data: {
                  employee_name: 'pathak',
                  id: "434",
                    salary: [{'march': 1100, 'april': 2200, 'may': 2300}]
                }

To achieve the desired outcome, you can utilize multiple instances of the reduce() method.

const data = [{
    employee_data: {
      employee_name: 'Rishi',
      id: "433",
      salary: [{
        'march': 1200,
        'april': 2000,
        'may': 2000
      }]
    }
  },
  {
    employee_data: {
      employee_name: 'pathak',
      id: "434",
      salary: [{
        'march': 1100,
        'april': 2200,
        'may': 2300
      }]
    }
  },
  {
    employee_data: {
      employee_name: 'partap',
      id: "435",
      salary: [{
        'march': 1200,
        'april': 2200,
        'may': 2300
      }]
    }
  }
];

const result = data.reduce((obj, user) => {
  obj[user.employee_data.id] = {
    "employee_name": user.employee_data.employee_name,
    "total_salary": user.employee_data.salary.reduce((total, current) => {
      return total + Object.values(current).reduce((num1, num2) => num1 + num2, 0);
    }, 0),
  };
  return obj;
}, {});

console.log(result);

To calculate the totals, utilize multiple reduce() functions.

 // loop through the data array
let result = data.reduce((accumulator, current) => ({ ...accumulator, 
 // merge with the accumulator by creating a new object with employee id as the key
  ...{ [current.employee_data.id]: {
        employee_name: current.employee_data.employee_name,
        // total salary is computed by summing all values in the salary object
        total_salary: Object.values(current.employee_data.salary[0]).reduce((sum, value) => sum + value, 0)
      }
    }
  }), {})

let data = 
    {
      employee_data: {
          employee_name: 'Rishi',
          id: "433",
          salary: [{'march': 1200, 'april': 2000, 'may': 2000}]
      }
    },
    {
        employee_data: {
          employee_name: 'pathak',
          id: "434",
            salary: [{'march': 1100, 'april': 2200, 'may': 2300}]
        }
    },
    {
        employee_data: {
          employee_name: 'partap',
          id: "435",
            salary: [{'march': 1200, 'april': 2200, 'may': 2300}]
        }
    }
]

// iterate through the data array
let output = data.reduce((b, a) => (
 // return the accumulator b, adding in...
  { ...b, ...{
  // a new object with the employee id as the key
      [a.employee_data.id]: {
        employee_name: a.employee_data.employee_name,
        // the total salary is summed through another reduce, this time, taking the Object.values() of salary and adding them together
        total_salary: Object.values(a.employee_data.salary[0]).reduce((d, c) => d + c, 0)
      }

let data = 
    {
      employee_data: {
          employee_name: 'Rishi',
          id: "433",
          salary: [{'march': 1200, 'april': 2000, 'may': 2000}]

        employee_data: {
          employee_name: 'pathak',
