JavaScript RegExp Example: Regular Expression Tester

Preview
Feel free to test JavaScript's RegExp support right here in your browser. Obviously, JavaScript (or Microsoft's variant JScript) will need to be enabled in your browser for this to work. Since this tester is implemented in JavaScript, it will reflect the features and limitations of your web browser's JavaScript implementation.
 

Determining JavaScript cookie support in client's browser

Preview
If your script relies on JavaScript cookies to store and persist information, it's a good idea to always make sure the user's browser has cookies enabled first. This tutorial shows you how to perform this detection.
 

JavaScript Promises

Preview
JavaScript is single threaded, meaning that two bits of script cannot run at the same time, they have to run one after another. In browsers, JavaScript shares a thread with a load of other stuff. What that stuff is differs from browser to browser, but typically JavaScript is in the same queue as painting, updating styles, and handling user actions (such as highlighting text and interacting with form controls). Activity in one of these things delays the others.

3 JavaScript ORMs You Might Not Know

Preview
When I wrote my first JavaScript lines, I never thought it would go beyond browser scripting and making interactive websites. I was wrong since JavaScript can be used literally everywhere: With an increased complexity of the application you’re developing, you would need something to help you deal with all the data you’re storing in the database, whether in a DB server (like PostgreSQL), in the embedded SQLite of mobile devices, or in the browser. Here comes the need for ORMs.

JavaScript Fundamentals: JSON Explained

Preview
JSON (JavaScript Object Notation) is a lightweight method of storing and sharing information: between the browser and a server, within JavaScript itself, and between programming languages. If you’ve read my previous articles on arrays, nested arrays and objects, you’re already halfway to understanding JSON. Unlike other syntax-heavy formats such as XML, JSON is already (mostly) JavaScript: there’s very little work for your script to parse through, interpret, or translate JSON.
 

Resources for JavaScript and DOM Compatibility Tables

Preview
Although Can I Use is great for many cutting-edge features, there’s still a lot of JavaScript and DOM stuff that’s not included in there. So what other options are there for looking up browser support for many different JavaScript and DOM features? I’m always doing research on various front-end technologies, but the one thing I’ve yet to find is a really good one-stop resource that lists browser support for all aspects of JavaScript and the DOM, including the various HTML5 APIs.
 

Browser Version Control

Preview
There are different browsers and versions out there. Thus you, the programmer, do not know what JavaScript capabilities the user has. Insuring that the scripts you write run in most users browsers can be done in a few different ways.One way is to use JavaScript to check which browser they are using, and then program accordingly. This is the most common way to avoid any scripting error.
