Thoughts on Software
var in JavaScript does not work particularly well, it confuses the heck out of beginners with it’s scope and the fact that it’s used everywhere for all concepts including constants make it difficult to identify the intent of each defined variable. ES6 introduces some new keywords that is easier to understand in terms of both scope and intent.
This is the second part of the JavaScript Quirks for Classical OO Developers. I will cover a bit of the most important things that you may have missed (I certainly did) with JavaScript as a C#/Java Developer without going into too much detail and some references for further reading.
During the past few months, I’ve been experimenting with a lot of new JavaScript libraries and frameworks. I have found it impossible to keep up with majority of developments in JavaScript, and the best tools coming out solve the problems they aim to solve but also have their downsides as any other tool.
I feel that JavaScript is a very misunderstood language – especially by many classical Object-Oriented developers (most that I know of anyway, myself included some years ago) that work primarily with C# or Java. This post isn’t to serve as a complete guide, it’s not a best practice guide, and it’s not for beginners – It’s a quick run through the JavaScript’s oddities classical OO developers may find.
