Creating a Template Engine Part 2: The Code

Last time we ripped off a bunch of libraries to create a string interpolation script and explained the composite pattern with a view to ultimately being able to parse and populate this template: <ul> ${#if responses.length} ${#each responses as response} <li>${}</li> ${#end each} ${#end if} ${#if !responses.length} <li><em>No responses</em></li> ${#end if} </ul> If you don’t […]

Creating a Template Engine Part 1: Groundwork

Although I strongly recommend using a popular, well tested engine, I believe that creating your own is a great learning experience. Since I’ve recently done this and couldn’t find any blog posts explaining the process, I thought I’d take the time to explain how one works, hopefully teaching a few budding JavaScripters looking to expand […]

Encapsulation Part 3: Objects

So far I’ve covered encapsulating arrays but objects are a far more common data type to encapsulate. The basic idea is to allow properties to be set, accessed, checked and removed without giving direct access to the object itself. You’ve almost certainly seen structures like this before. For consistency, setting will return the instance and […]

Encapsulation Part 1: Overview

Encapsulation is one of the four major principles of object-oriented programming (the others are abstraction, inheritance and polymorphism which I might cover in a later post). The basic idea behind encapsulation is to provide access to data while still hiding or protecting it. In this series of blog posts, I’ll show how this is done; […]
