In vanilla JavaScript, you can use the Array.concat() method to flatten a multi-dimensional array. This method works in all modern browsers, and IE6 and above.Here is an example:const animals = [ ['🐍'], ['🐢'], ['🐝'], ['🐉'], ['🐋'] ]; const flattened = []....
如何用 JavaScript 将 [1,2,3,[4,5, [6,7]], [[[8]]] 这样一个 Array 变成 [1,2,3,4,5, 6,7,8] 呢?传说中的 Array Flatten。 处理这种问题,通常我们会需要递归,来让程序自己按照一种算法去循环。在某书说写着,“递归是一种强大的编程技术”,好吧,她不仅仅属于 JavaScript。递归可以很难,...
在JavaScript中可通过Array.prototype.flat(Infinity)直接实现,而Java等强类型语言则需要借助迭代器模式处理。 反转:顺序重构的艺术 反转(Invert)操作在扁平化后的数据结构上执行顺序翻转。对于上述结果[1,2,3,4,5,6],反转后得到: [6,5,4,3,2,1] 高效实现需注意: 原地...

numpy中meshgrid使用 meshgrid的作用适用于生成网格型数据。具体看图说明 meshgrid对于传入的第一个x_array数组,会以他的列为基础,对于第二个传入的y_array会以他的行为基础。最后将其进行输出。具体为什么会这么输出,还在探究,先做个笔记,防止忘记。...
