148. create a counter object

Here is one possible solution using a closure:

function createCounter() {
  let count = 0;
  return {
    get count() {
      return count++;
    },
    set count(value) {
      console.error('Cannot assign a new value to count.');
    },
  };
}

Explanation:

• The function createCounter returns an object that contains two properties: a getter and a setter for the count property.
• The count variable is initialized to 0 using a closure. This variable is private and cannot be accessed from outside the object.
• The getter function returns the current value of count and increments it by 1.
• The setter function throws an error when someone tries to assign a new value to count. This makes count a read-only property.
• The console.error method is used to log the error message to the console.

Note: There are other ways to implement a counter object in JavaScript. This is just one example.
