Worker class and average salary

Write a class Worker with the fields name (string), age (number) and salary (number).

• Constructor: new Worker(name, age, salary).
• A getter and a setter for every field: worker.salary returns the salary, worker.salary = 2000 changes it. Use get and set, not plain properties.
• toString() returns a string exactly like Worker{name='Ann', age=30, salary=1500}. Numbers are printed the default JavaScript way: 1500.5, not 1500.50.
• The function averageSalary(workers) takes an array of Worker objects and returns the average salary, not rounded. For an empty array it returns 0.
• Create an array workers with at least three Worker objects.
