We can excess the name of employee and their salary and change their name using for loop. We use for loop for changing their name with a, b, c, d

const employeeInfo = [
    {name: "Alex", location: "Chicago", salary: 8000,},
    {name: "Emma", location: "New York", salary: 7500,},
    {name: "Max", location: "Los Angeles", salary: 8200,},
    {name: "Liam", location: "Seattle", salary: 7900,}
  ];

  let newTable = {};
  for(let index = 0 ; index < 4 ; index++) {
    const employee = employeeInfo[index];
   
    const names = ['a','b','v','d']
    const currentName = names[index];
   
    newTable[currentName] = employee.salary;
  };

  console.log(newTable);


Result:
