巧用 Array.prototype.reduce 替代 map 实现数组元素转换

```javascript function transformArray(arr, func) { return arr.reduce((accumulator, currentValue) => { accumulator.push(func(currentValue)); return accumulator; }, []); } let inputArray = [1, 2, 3]; let transformFunction = function(x) { return x * 2; }; console.log(transformArray(inputArray, transformFunction)); ``` ######[AI写代码神器 | 91点数解答 | 2024-11-07 15:34:51]
