在JavaScript里,我们常在管理命名空间时使用单例模式,它可以降低你在代码中创建全局变量的数量。单例模式在JavaScript里要比在其他语言中更有用,因为它可以用命名空间来降低全局变量所带来的风险。 一个基本的单例模式 这是一个最基本最简单的用JavaScript实现的单例模式。它就是一个简单的有一些方法和属性的对象字面...
在JavaScript 中,Promise 是一种处理异步操作的方式。Promise 可以让我们更加优雅地处理异步操作,而不需要使用回调函数嵌套。 ● Promise 是一门新的技术(ES6 规范),是 JS 中进行异步编程的新解决方案(旧方案是单纯使用回调函数,容易形成回调地狱) ● 常见异步操作:①fs 文件操作 ②数据库操作 ③Ajax ④定时器 ...
