关键词:lodash.flattenDeep 实现
以下是用 JavaScript 手写实现类似于 lodash.flattenDeep 的函数来将数组递归展平为一维数组:
lodash.flattenDeep
function flattenDeep(arr) { let result = []; for (let item of arr) { if (Array.isArray(item)) { result = result.concat(flattenDeep(item)); } else { result.push(item); } } return result; }
你可以使用以下方式测试这个函数:
const nestedArray = [1, [2, [3, [4]]]]; const flattenedArray = flattenDeep(nestedArray); console.log(flattenedArray); // [1, 2, 3, 4]
