TypeScript

数据类型

基本数据类型：

• Boolean
• Number
• String
• Array
• Function
• Object
• Symbol
• undefined

TS实现睡眠

Sleep = (ms:number)=> {
	return new Promise(resolve=>setTimeout(resolve, ms))
}
async jump(){
	this.router.navigate(["/loading"]);
	await this.Sleep(1500);
	this.router.navigate(["/detail"],{
		queryParams: {
				name: "kitty"
		}
	})
}

fs读取json文件数据

let fs = require("fs")
import * as fs from 'fs'
if (fs.existsSync('./baseurl.json')){
  const baseurl = JSON.parse(fs.readFileSync('./baseurl.json','utf-8'))['baseurl']
  console.log(baseurl);
}
