78.createCounter

Write a function named createCounter that receives a number as a parameter.

The function should return an object representing a counter, with the following 3 properties:

• a function named getValue that returns the current value of the counter
• a function named increment that increases the counter value by 1
• a function named decrement that decreases the counter value by 1

const counter = createCounter(11);

counter.increment();
counter.increment();
counter.increment();

console.log(counter.getValue()); // should print 14

counter.decrement();

console.log(counter.getValue()); // should print 13
