Challenge

JS Challenges all about solving problems that arises from it. So this time let’s try to make our own implementation of Array and we should be able to run this code block below:

const office = array("Dwight Schrute", "Jim", "Kevin", "Angela", "Pam"):
 
// Add to array (.push)
office.hire("Michael", "Oscar", "Ryan", "Andy", "Toby");
// Remove from array
office.fire("Kevin");
 
// Filter array (.filter from array)
const meetingRoom = office.meeting((employee)=> {
  return employee !== "Michael";
});
 
// meetingRoom =>  All the employees except Michael

1. array(...args) should create an array and return that array.

2. hire(...args) function should push to array.

3. fire(arg) function should remove a given element from the array

   • Extra 1: If you pass exact object that is in the array it will remove that.

   • Extra 2: It can take callback function to remove the element(s). Ex: office.fire((employee)=> boolean))

4. meeting(callback) should filter the array.

If you want to make it more challenging you can make every function is type-safe and typed correctly. Good luck and have fun 🥳
