Another calculator. Now the task is more difficult.

Task description:

Create a makeCalculator function that returns an object that has the following fields:

• Methods: add, subtract, multiply, divide, reset, operate.
• The result property is initially 0.

How the calculator will work:

• Each operate call takes a callback and a number and sets the appropriate value to the result property.
• The reset method resets result value to 0.
• add, subtract, multiply, divide are passed as callbacks to operate method.
• The operate and reset methods can be called in a chain.

Example:

const calculator = makeCalculator();

calculator.operate(calculator.add, 21)

console.log(calculator.result); // 21

calculator.reset()
console.log(calculator.result); // 0

calculator
  .operate(calculator.add, 10)
  .reset()
  .operate(calculator.subtract, 20)
  .operate(calculator.divide, 5)
  .operate(calculator.multiply, 7)

console.log(calculator.result); // -28
