首先,我们创建一个SharedArrayBuffer,其内存需要包含100个32位整数。接下来创建一个Int32Array实例,它将用缓冲区来保存其结构,然后用一些随机数填充数组并将其发送到父线程。 在父线程中: import path from 'path'; import { runWorker } from '../run-worker'; const worker = runWorker(path.join(__dirname...

2.5 Array 类型 2.6 Enum 类型 使用枚举我们可以定义一些带名字的常量。 使用枚举可以清晰地表达意图或创建一组有区别的用例。 TypeScript 支持数字的和基于字符串的枚举。 1.数字枚举 默认情况下,NORTH 的初始值为 0,其余的成员会从 1 开始自动增长。换句话说,Direction.SOUTH 的值为 1,Direction.EAST 的值为...

noUncheckedIndexedAccessis intended to prevent all accidental out-of-bounds access on arrays. Because array mutationcouldoccur at any time, it doesn't make any exceptions for things likelengthchecks. In order to ensure that the flag doesn't have any "gaps", requests to change the logic to ...
