Deleting element and changing element property in an Array of objects

Question

So there is an array of object called employees that has employee's credentials. I am supposed to delete the object if the employee's name is Theo, and if the employee's name is Lorie I should change the department's property to 'HR' I've tried using a for loop to go through the objects in the array and change their properties. but it would not return the iterated array. maybe I need to use the.reduce() method Here is the code I've tried

Answer 1

It should be working!

Your array of objects.

var employees = [
 {
  "firstName": 'Von',
  "lastName": 'budibent',
  "email": "email@mail.com",
  "departement": "Sales"
 },
 {
  "firstName": 'Theo',
  "lastName": 'Trill',
  "email": "email@mail.com",
  "departement": "Services"
 },
 {
  "firstName": 'Lorie',
  "lastName": 'Trill',
  "email": "email@mail.com",
  "departement": "Research and Development"
 }
];

Then you need to filter by firstName and then mapping the data.

var adjustedEmployees = employees
 .filter(employee => employee.firstName !== 'Theo')
 .map((employee) => {
   if (employee.firstName === 'Lorie') employee.departement = 'HR';
   return employee;
 });

Answer 2

//I needed to use a function with no parameters, I figured out how to do it.

Answer 3

//Remove employe with firstname 'Theo'
var result = employees.filter(employee => employee.firstName !== 'Theo');
//Change department of Lorie to 'HR'
result.forEach(el => {
  el.departement = el.firstName === 'Lorie' ? 'HR' : el.departement
})
