7 Resources Every JavaScript Developer Should Know
A web developer today is expected to be an expert in every aspect of their craft and JavaScript is no exception. Years ago JavaScript seemed to be more of an annoyance, producing those trailers at the bottom of the browser. This has changed and JavaScript is a first-class citizen as a functional programming language and what seems like an unlimited number of resources covering the language. I have been doing more and more JavaScript lately, both on the front-end and some node.js...

Writing great JavaScript
I probably could have named this post something like “Writing clean, validating and portable JavaScriptâ€, but that would be no where near as catchy. The problem with “great†is it means different things to different people. I am going to show you my idea of great which may differ from many developers views, but I hope it helps someone improve their code. So what’s the point in this, why can’t you just carry on writing JavaScript as you have been for a...

Java vs F#
Dr Cliff Click of Azul Systems, specialists in manycore JVM systems, recently published a blog post about the performance of Java compared primarily to C and C++ but also discussing C# and .NET. Three of Cliff's comments are of particular interest:Under the heading "Places where C/C++ beats Java for obvious reasons":"Value Types, such as a 'Complex' type require a full object in Java." - Dr Cliff ClickWhat Cliff forgot to mention is that .NET also provides value types and a far more compell...

JavaScript tips both novice and veteran developers can benefit from
In this post, we will share some less known but powerful JavaScript tips which can benefit both novice and veteran JavaScript developers. 1. Truncate array with array length We all know that object are passed by reference in JavaScript, but we may be bitten by this rule. Please check below example: var arr1 = arr2 = [1, 2, 3]; //Change arr1 arr1 = []; // arr2 will still be [1,2,3] arr1 and arr2 point to the same array [1,2,3] initially, later when arr1 repoints to [], the reference to arr2 is n...

Get hostname from a URL using JavaScript
Sometimes we may have strings which contain some UR;s and we may want to retrieve the hostname from the URLs for some statistic use. For example, we may have a URL : http://www.example.com/aboutus.html. We may want to retrieve the www.example.com from the URL. How? Use regular expression. Here I give an example using JavaScript. If you want to check whether a string is a URL or not. Refer to Detect URLs in a Block of Text. In JavaScript, we can have a regular expression like var pattern=/(.+:\/\...

Why you should be careful about optimizations
In one of my current javascript projects, I have to deal with 3D voxel coordinates. And, sometimes, I have floating points coordinates which must be converted to integers in order to convert them into proper array index. Javascript is a wonderful language, really. However, implementations are sometimes weird, and the way to do something can sometimes have very huge impacts on the performances. Worse, sometimes the classical way is more expensive than the tricky one. So, some peo...

Going Simple with JavaScript
I was making a change to a page that needed to pull from a remote API and make changes to various parts of the page. Sounds like the time to pull out jQuery and Ajax, doesn't it? Instead, I just used old fashioned JavaScript. Actually, I used new fashioned JavaScript. Browsers haven't stood still in the advent of libraries and frameworks. As a result, we can take advantage of those features when we need to bake in a little extra. Some JSONP The first step was to get the JSONP call execu...
