When using recursion, you must be mindful of the dreaded infinite loop. Using the recursive function that we’ve built up over the previous lessons, we look at how a simple duplicated configuration item could cause chaos for our program as it has no c…

Recursion is a technique well suited to certain types of tasks. In this first lesson we’ll look at solving a problem that requires the flattening of arrays without using recursion. Showing the shortcoming of a non-recursive solution first will help y…

If you use cookieless session ID and deploy them on Azure, you might get infinite loop when you query your web site, and browser would down. In this scenario, you need to overwrite ASP.NET default ISessionIDManager. In method GetSessionID, your could…

Recursion is when a function calls itself. This self calling function handles at least two cases, the recursive case and the base case. People seem to either love it or hate it because it can be difficult to understand and implement correctly. Let’s…

引言 相信所有学过 JavaScript 都知道它是一门单线程的语言,这也就意味着 JS 无法进行多线程编程,但是 JS 当中却有着无处不在的异步概念 .在初期许多人会把异步理解成类似多线程的编程模式,其实他们中有着很大的差别,要完全理解异步,就需要了解 JS 的运行核心——事件循环(event loop).在之前我对事件循环的认识也是一知半解的,直到我看了 Philip Roberts 的演讲 What the heck is the event loop anyway?,我才对事件循环有了一…

参考地址:http://www.ruanyifeng.com/blog/2014/10/event-loop.html 一.为什么JavaScript是单线程? JavaScript语言的一大特点就是单线程,也就是说,同一个时间只能做一件事.那么,为什么JavaScript不能有多个线程呢?这样能提高效率啊. JavaScript的单线程,与它的用途有关.作为浏览器脚本语言,JavaScript的主要用途是与用户互动,以及操作DOM.这决定了它只能是单线程,否则会带来很复杂的同步问题.比如,假定…

An introduction to the Web Audio API. In this lesson, we cover creating an audio context and an oscillator node that actually plays a sound in the browser, and different ways to alter that sound. var context = new window.AudioContext() || new window.…
