TypeScript 类型编写指南

本文主要作为平时在 TypeScript 代码中编写类型以及对 TypeScript 代码进行 review 时候的参考手册，并非强制执行的规范，也不涉及纯代码风格以及代码逻辑上的指导。

本文内容参考了下面几个手册，所以强烈建议能够同时阅读完这几个手册。如果大家对 TypeScript 的一些基础用法和特性还不熟悉，也建议先阅读第一个 TypeScript 手册。

	const exec = util.promisify(child_process.exec);

	glob('src/*/.js', async (err, files) => {
	console.log(files);
	for (let file of files) {
	await exec(`git mv ${file} ${file.replace('.js', '.ts')}`);
	}

	const fetch = require('node-fetch');

	const MILESTONE_NUMBER = 15;


	function assembleIssues(issues) {
	return issues.map(issue => {
	if (issue.state === 'open') {
	return '#' + issue.number + ' ' + issue.title;
	}
