If you are working on a project by your own, you might not worry about the structure, convention and organisation of your code given you fully understand how it works. But working in a team environment it is necessary to make sure that your team members understand your code, easily adaptable and extensible so the importance of maintainable javascript is inevitable.

When deploying software manually, the tendancy is to deploy once a month or perhaps once every two or three months. Deployment doesn’t stop for production only, there are test, staging and production as well.

When your site grows, the CSS can grow along with it, and the maintenance is no longer trivial. You could break your CSS in to different files and use @import to structure it into one file. But this doesn’t resolve all your architecting and maintenance problems.

There are more than one way to make AJAX calls in jQuery. In this tutorial, let’s compare these methods as well as inspect the AJAX calls with Firebug.

Sass is a scripting langauage that is interpreted into CSS. Sass stands for Syntatically Awesome Stylesheets. Sass consists of two syntaxes. The original syntax, called “the indented syntax”, uses a syntax similar to Haml. It uses indentation to separate code blocks and newline characters to separate rules.

Deferred and promise are part of jQuery since version 1.5 and they help in handling asynchronous functions like Ajax.

Sass enables your you to separate your stylesheets into individual files, and then you can use the @import directive to include your individual files into one master stylesheet.

Ruby is a dynamic, reflective, object-oriented, general-purpose programming language. It was designed and developed in the mid-1990s by Yukihiro “Matz” Matsumoto in Japan.

Many objects in Node emit events: a net.Server emits an event each time a peer connects to it, and fs.readStream emits an event when the file is opened. All objects which emit events are instances of events.EventEmitter.

Native CSS variable support is still in its infancy, but Sass affords us a way to set reusable values.

Writing jQuery in CoffeeScript, further simplifies the syntax. The jQuery(function($)) can be written as jQuery($) -> or simply $ ->.

HTML5 offers new elements for improving semantics of code as well as better document structure. These elements could now be used to replace traditional HTML code like <div id=”nav”> <div class=”header”> <div id=”footer”>

A common problem with float-based layouts is that the floats' container doesn't want to stretch up to accommodate the floats. If you want to add, say, a border around all floats (ie. a border around the container) you'll have to command the browsers somehow to stretch up the container all the way.

In this article, we are going to study REST, routes, constraints, and namespaces. Before we dive into these concepts let’s take a look at how web-based services in the perspective of web users.

If you are thinking of consuming data in your Ember application, you can store them in fixtures. But what if you want to fetch data from a server?

We have learned about the new features ES6 brings us in ES6 New Features article. In this post, we will go through the advanced features of ES6 and how we can implement them.

A tail call happens when a function Foo calls a function Bar as its final action. At that point Foo stops and passes the execution to function Bar and disappears not having to do anything from there onwards.

Array comprehension is creating a list B based on another list A, where each entry of B is the result of a custom operation performed on the items of list A.

Proxies enable you to intercept and customize actions performed on JavaScript objects such as `getter` and `setter` for getting and setting properties. This is really helpful in scenarios like JSON based API interaction where you have to customize data coming back from the API.

Local storage is more secure, and large amounts of data can be stored locally, without affecting website performance. Unlike cookies, the storage limit is far larger (at least 5MB) and information is never transferred to the server.

Prototype objects are just simple JavaScript objects and may have their own prototypes. If a prototype has a non-null reference to its prototype, and so on, this is called the prototype chain.

ECMAScript is a object based language. An object has a built-in property named constructor.

In a scaling project, the way CSS spans out can bring us various problems. Let’s look at these issues, and discuss them in detail.

JavaScript classes are simply syntactic sugar over existing JavaScript prototype chain. But classes give you a cleaner way to organise your code, and make it slightly easier for the beginner or people who are familiar with class oriented languages to read JS and understand.

In this tutorial, I’ll show you how to install Gulp and create a simple configuration file to get your feet wet with this great new task runner.

If you are familiar with JavaScript, you have probably known the term scope. If you are familiar with other languages, you would know that a scope of a variable is to the nearest block – block scope. But JavaScript is different. A variable created with var will be scoped to the nearest parent function.

Sass control directives helps creating libraries for reuse and distribution, there by contribute to writing leaner Sass. Advanced frameworks use mixins. These mixins use directives such as @if, @for, each and @while.

A module is a self-contained unit of code, which is usually stored in a file. In ES6, modules get language-level support for component definition. Modules export values, which can then be imported by other modules.

To loop over an array or a collection JavaScript has been traditionally using for loops. ES5 introduced the for ..each loop. But ES6 introduces a little shorter version, a new interface for iteration called Iterable.

Flux is the application architecture that Facebook uses for building client-side web applications. It complements React’s composable view components by utilizing a unidirectional data flow. It’s more of a pattern rather than a formal framework.

Many programming languages support the concept of a default argument for a function parameter so that the caller does not always need to specify the argument value. Unfortunately, ES5 does not have a default argument support in its syntax. ES6 functions have come a long way by taking aboard the years of complaints and improving parameter handling that is less error-prone and more powerful.

Isomorphic JavaScript means that we get to share the same code on the client and on the server. So basically, you are rendering your application markup on the server and piping it down as complete HTML to the browser.

Template strings in JavaScript consist of literal text, and placeholders where the runtime can evaluate an expression to inject data into the text.

ES6 is here and now. So writing React JS components in ES6 will be beneficial considering the new features ES6 brings to us.
