  Prototypes in JavaScript

Following on from his previous article, David Chisnall explores JavaScript as an example of prototype-based object orientation. In this article, he shows how it's possible to implement more complex object models on top of this simple abstraction.My previous article, Prototypes and Object Orientation, considered the differences between class-based and prototype-based object orientation. In this article, we'll look in a bit more detail at the workings of the JavaScript object model, since it'...

  CSS3 animation vs CSS3 transition

Both CSS3 animation and CSS3 transition can be used to transition an element in a webpage. They can be used to transition some CSS properties within a given period of time. They have many similarities. They do have a few differences as well. So an user needs to understand the differences between them in order to better use them in different scenarios. First, let's see an example on how to change the width of a div from 100px to 200px within 2 seconds when hovering on it. With CSS3 animation , th...

  Understand Virtual DOM

With the popularity of React, the internals and implementation of Virtual DOM has becoming top discussed topic in tech communities and interviews. This post will give an introduction of Virtual DOM and how to implement a simple Virtual DOM logic. How to understand Virtual DOM In early days, front end developers would update a webpage view based on the data status change(usually after making AJAX call). But it brings performance penalties when there is frequent update as it would cause page reflo...

  I’m too lazy to be a HTML developer

There’s no denying it. I’m just to damn lazy to be an HTML developer. This really sunk in when I looked at a tutorial for doing a jQuery Lightbox – for a client project. The tutorial was titled “Super Simple Lightbox with CSS and jQuery” but after reading it over I thought a better title would be “A really freaking hard tutorial on the inane intricacies of doing something that looks simple but in reality is a skein of HTML, Javascript and CSS that no...

  Java Polymorphism and Overriding Methods

Most Java developers will be familiar with polymorphism – we’ve all seen the example of the Dog and Cat classes inheriting from some abstract Animal class and having their say() methods produce different results. But it’s still worthwhile to look at a few simple examples to reinforce the concepts.First, we define a simple class with one instance method and one static method.public class A { public String getName() { return "I a...

  What I learned interviewing with Google

Over the last few weeks I’ve been interviewing with Google for a job doing primarily JavaScript development. I didn’t end up getting the job but I thought I would share the process of interviewing for Google as it was both very exciting and a humbling experience. I can’t reveal everything as I’m under a few NDAs. I’m not going to mention the products or teams that I was interviewing for but you may be able to guess. For those that don’t know me, I...

  Why using anchors as buttons sucks

So let's say you're an awesome web developer making an awesome web app. One day, you add a link in the web app that has an event handler instead of an href. Testing it, you realize that your cursor doesn't change when hovering over it, unlike a normal link. You think for a minute and then give it a cursor:pointer style, which fixes the issue. You are happy.The next day, QA informs you that the link cannot be tabbed to. Confused, you do some research and find a solution to the problem: Sim...

  A Peek Inside the Erlang Compiler

Erlang is a complex system, and I can’t do its inner workings justice in a short article, but I wanted to give some insight into what goes on when a module is compiled and loaded. As with most compilers, the first step is to convert the textual source to an abstract syntax tree, but that’s unremarkable. What is interesting is that the code goes through three major representations, and you can look at each of them. Erlang is unique among functional languages in its casual scop...

  Strict mode in JavaScript

1. Introduction In addition to normal mode, ECMAScript 5 includes the other mode : strict mode. It means it will make JavaScript codes execute in a more strict environment. The purposes to have strict mode are: Remove some unreasonable and parts of JavaScript syntax. Reduce some of the quirk behaviors. Remove some insecure parts of code execution. Make the execution environment more secure Improve interpret efficiency and increase the execution speed Build foundation for future JavaScript versi...
