Explanation:\n\n1. The createCounter function takes an integer n as input and initializes a counter variable to n.\n2. It then returns an anonymous function that takes no arguments.\n3. When the returned function is called, it returns the current value of counter and then increments counter by 1 using the post-increment operator (counter++).\n4. Since counter is a local variable in the scope of the createCounter function, it does not modify the original input n.\n\n\nWe can directly return n++, but it is better not to modify the given input. Hence we store it in another variable and then return.\n\nAlso, if any of you is having difficulty to understand the count++ thing then you can first increment count and then return count - 1. Like this:\ncount++;\nreturn count - 1;\n\n# Code\n```\n/**\n * @param {number} n\n * @return {Function} counter\n */\nvar createCounter = function(n) {\n    var count = n;\n    return function() {\n        return count++;\n    };\n};\n\n/** \n * const counter = createCounter(10)\n * counter() // 10\n * counter() // 11\n * counter() // 12\n */\n```\n\nPlease upvote if found helpful. :)
