typescript中别名(alias),jest,ts-node,apidoc等相关配置及示例如何配置别名

（花色简称： 红桃-H, 梅花-C, 方块-D，黑桃-S）定义一个函数，让用户选择两张扑克牌， 函数返回所有可能的顺子组合， 如果能形成同花顺，在开始前打印(SF).然后计算每一种顺子不同花色的排列组合；顺子的长度相当于for循环的层数 ，也就是递归的次数；，利用reduce去递归，比起正常递归调用，思路更加清晰， 每一步结果一个自动传下去；打印结果： SF->DA, D2, D3, D4, D5。顺子固定长度为5张牌，不用考虑K之后到A的情况。是从1开始的，而不是0开始。顺子就是一个排列组合问题，

如果一个值是联合类型，我们只能访问此联合类型的所有类型的共有属性。

【代码】Token刷新处理。

es6 WeakMap的使用

const PENDING = 'PENDING';const FULFILLED = 'FULFILLED';const REJECTED = 'REJECTED';const resolveMyPromise = ( myPromise: MyPromise, x: any, resolve?: (result: any) => void, reject?: (err?: any) => void,) => { // 如果 x === myPromise,则会造成循

关于typescript的类型定义的学习心得

koa2中的如果所有中间件走完 没有设置ctx.body则会响应404import recorders from '../../recorder';import { IMiddleware } from 'koa-router';import https from 'https'; const getStreamTexts: IMiddleware< any, { query: { envName: string; streamId: string; startI

this相当于某个作用域的上下文；bind(this)相当于在运行时传入一个上下文替换原有this；而箭头函树相当于在函数作用域内锁定上下文this;class A { public name: string; constructor() { this.name = 'a'; } public a() { console.log(this.name); }}class B { public name: string; constructor() { this.name

export default class A { public Resume: () => void; public Paused: Promise<void>; constructor() { } public Start() { process.nextTick(async () => { await (this.Paused || Promise.resolve()); console.log('runing job'); // 此处必须要用set

1.流式读取：const readstream = fs.createReadStream('test.mp4'); let i = 0; console.time('readtime'); readstream.on('readable', () => { let chunk = readstream.read(8192 * 1024); while (null !== chunk) { console.log(`file${++i} md5: ${md5(chunk)}`);

在incude中添加声明文件夹：types/*添加ts的配置文件：// tsconfig.json{ "compilerOptions": { "experimentalDecorators": true, "module": "commonjs", "esModuleInterop": true, "allowSyntheticDefaultImports": true, "target": "es6", "noImplicitAny": true, "moduleRe

安装emscriptenwindows系统 建议采用wsl安装比较方便；示例test.c:#include <stdio.h>#include <emscripten/emscripten.h>int EMSCRIPTEN_KEEPALIVE myFunction(int argc, char **argv){ printf("这是一个测试函数\n"); return 0;}编译： 会生成test.js test.wasm;（详细编译命令看官网） emc
