There are several possible ways to write object-oriented JavaScript code, but they all turn around the concept of the “Function” class: function Thing() { var privateField = “PRIVATE”; var self = this; // See below for more explanations about “this” [...]

As I said yesterday, JavaScript is the world’s most misunderstood language, which means that you must unlearn what you have learned. However complicated it might seem at first, it is quite easy to write and understand the most complex of JavaScript codes with just some examples. Just a few observations before starting: Semicolons (;) are [...]
