鉴于for 和 for-in 都不特别适合在 Arrays 上循环,因此在ECMAScript 5中引入了辅助方法:Array.prototype.forEach. const arr = ['a', 'b', 'c']; arr.prop = 'property value'; arr.forEach((elem, index) => { console.log(elem, index); }); // Output: // 'a', 0 // 'b', 1 //...

However, with multidimensional arrays, using a nested for loop gives you more control over the order in which to process the array elements: C# Copy int[,,] array3D = new int[,,] { { { 1, 2, 3 }, { 4, 5, 6 } }, { { 7, 8, 9 }, { 10, 11, 12 } } }; for (int...
