在JavaScript 编程中,我们都习惯于创建和使用一维数组。这些是包含元素(相似数据类型或多种数据类型的元素)的数组。 但知道 JS 中存在二维数组(2D array)也很好。 在本文中,您将了解什么是二维数组以及它们在 JavaScript 中的工作原理。它与其他编程语言有很大不同,因为从技术上讲,JavaScript 中不存在二维数组。 什么是二
Now that we have created our 2D array in JavaScript, let us learn what operations can be performed on this array. We would look at how to access, insert, remove and update elements in our array. So, we create an array and initialize it with values as below: var array2D = new Array(...
Regular arrays in JavaScript are one-dimensional. We create regular arrays by either using the literal notation or using the Array constructor as shown below: 1 let numbers = [1, 2, 4, 59, 589, 126]; 2 let names = new Array('Peter', 'Adam', 'Andy', 'Jake', 'Andrew'); 3 ...

这样虽然可以避免内存访问错误,但是仍有可能会生成一些无效数据。譬如,你把 JavaScript 端返回的 Float32Array 的最后 3 个元素打印出来,它们是247055、248056、608032;如何避免因数组索引越界而可能发生的无效数据问题呢?可以用卫语句提前返回: fnmain(/*...*/){if(global_id.x>=arrayLength(&output)){return;}...
