\n# Approach\nThe postfix increment operator (n++) is used to increment the value of the n variable.\n\nThe postfix increment operator is denoted by two plus signs (++) placed after the variable. Here\'s how it works:\n\nWhen the n++ expression is encountered, the current value of n is returned as the result of the expression.\n\nAfter the value is returned, the n variable is incremented by 1.\n\nIn the context of the code, the postfix increment operator is used within the inner function returned by createCounter:\n\n# Complexity\n- Time complexity:\nThe time complexity of the createCounter function itself is constant since it only returns a function without performing any iterative or recursive operations. Thus, the time complexity is **O(1)**.\n\n- Space complexity:\nThe space complexity of the createCounter function is also constant. It does not create any additional data structures or variables that grow with the input. Therefore, the space complexity is **O(1)**.\n\n# Code\n```\n/**\n * @param {number} n\n * @return {Function} counter\n */\nvar createCounter = function(n) {\n    return function() {\n        return n++;\n    };\n};\n\n/** \n * const counter = createCounter(10)\n * counter() // 10\n * counter() // 11\n * counter() // 12\n */\n```
