# Intuition\nThe code appears to implement a simplified version of the `reduce` function commonly found in JavaScript arrays. The `reduce` function is used to reduce an array to a single value by applying a specified function to each element of the array.\n\n# Approach\nThe approach seems straightforward. The function `reduce` takes an array `nums`, a function `fn` (which is presumably the reducer function), and an initial value `init`. It iterates over each element of the array, applying the reducer function to the accumulator and the current element. The result is then stored in the accumulator, and the process continues until all elements are processed. The final accumulated value is then returned.\n\n# Complexity\n- Time complexity: \\(O(n)\\), where \\(n\\) is the length of the input array `nums`. This is because the function iterates through each element of the array once.\n\n- Space complexity: \\(O(1)\\), as the function uses a constant amount of space (only the `accum` variable) regardless of the size of the input array.\n\n# Code\n```javascript\n/**\n * @param {number[]} nums\n * @param {Function} fn\n * @param {number} init\n * @return {number}\n */\nvar reduce = function(nums, fn, init) {\n    let accum = init;\n    for (let i = 0; i < nums.length; ++i) {\n        accum = fn(accum, nums[i]);\n    }\n    return accum;\n};\n```\n\nThe code seems correct and follows the typical pattern of a reducer function. The result is returned after iterating through all elements of the array.
