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: AI检测代码解析 import path from 'path'; import { runWorker } from '../run-worker'; const worker = runWorker(path.join(__dirname, 'worker.js'), (err, { arr }) => { ...

TypeScript 4.9 adds the other half, and now provides "Remove Unused Imports". TypeScript will now remove unused import names and statements, but will otherwise leave the relative ordering alone. Copy import{ Moose, HoneyBadger }from"./zoo";import{ foo }from"./helper";letx: Moose | Honey...

建立抽象基类(Element),目的:与万物之母Object建立中间保护层,便于后期可以用instanceof区分自建类及其它对象类,另抽象部分虚拟函数; 建立实体基类(EntityElement)与配置基类(ConfigElement),都继承自Element,此目的可区分实体与配置的不同行为,比如后期实体序列化到数据库,配置序列化到JSON; 实体基类(EntityElement),抽象...
