This is consistent with the behavior of the built-in flat() method. Infinity can be used to flatten completely. Uses spread syntax (...): This makes the array merging more efficient than using concat(). Handles sparse arrays: Correctly handles arrays with empty slots (e.g., [1, 2, ,...

to flatten the array by spreading the elements ofthe sub-arrays into a new array. Additionally, we can use the () method to merge multiple arrays into a single array, effectively flattening it. 中文翻译: 在JavaScript中,拉平数组的一种方法是使用()方法。该方法会创建一个新数组,将所有子数组...
arr: the input array. Both functions assume that all nested arrays have the same length (i.e., the input array is not a ragged array).Examples var naryFunction = require( '@stdlib/utils-nary-function' ); var abs = require( '@stdlib/math-base-special-abs' ); var flatten5dBy = requ...

首先,我们需要定义一个名为`flattenArray`的函数,该函数接收一个参数`arr`,表示待处理的数组。函数的目标是将所有的嵌套数组合并成一个平铺的数组,并返回这个结果。 ```javascript function flattenArray(arr) { // 空数组用于存储结果 let result = []; // 使用循环遍历传入的数组 for (let i = 0; i <...
