JavaScript for Line of Business Applications

Instead of using loops, JavaScript Array object is quite powerful to create sequences. What about some more complex series and not just a list of consecutive numbers or letters? Fortunately, we still have other Array’s functions such filter, map, every, and reduce at our disposal. Those can be used to generate a list of prime numbers, compute the factorial, and produce the Fibonacci series.

Hakitzu: Code of the Warrior is a fun way to learn to program JavaScript. In a unique twist, as you’re learning to build your ultimate robot warriors, you’re also learning JavaScript coding. Become the best coder in the land, and you’ll find yourself on the pathway to victory.

Thanks to the wide adoption of libraries like jQuery and Mootools, JavaScript’s popularity has skyrocketed in the last few years. However, in the process, an interesting thing occurred: many newer developers are learning these libraries without taking the time to actually learn about raw JavaScript techniques. What percentage of jQuery users don’t know how to fade out an element with only raw JS? My guess is that it’s much higher than many would think.

Even if you’ve done very little JavaScript, you should be familiar with callbacks, which are used heavily for managing asynchronous operations in JavaScript. We’re going to look at an alternative way to handle such asychronous code by using Promises. The examples I’m going to cover are going to use Node.js, but the techniques and libraries involved work equally well for client side JavaScript too. And, you definitely don’t need be an expert on Node.js to follow this article.

A number of people, myself included, have a hard time getting started with test driven development (TDD). The issue lies in that it’s difficult to wrap your head around something that is rather non specific in its implementation and it is usually described as “writing your tests before you write your code”.

When developers hear “Write your tests before you write your code”, then they look at their previous test suite they wonder… “How can I possibly write this without having written the code first?

This isn’t a reference guide, programming tutorial or detailed overview. It’s a Javascript refresher, assuming you know another programming language and puts all the information in one place (just ctrl+f to find!). Javascript has nothing to do with Java, isdynamically typed and has C-like syntax.

We're a growing community of developers united to push the boundaries of HTML5 and revolutionize digital experiences.

Our community is built on developer stories, showcasing great work, and cultivating forward-thinking ideas. We're spreading the word throughout the global community.

Uniting developers across the world, we can better shape the future of HTML5. We share a common goal of consistently pushing the limits of web and cross-platform app technology.

Really the basics of programming in JavaScript in easy to learn video series.

In this article I have tried to capture the common design and coding mistakes JavaScript developers tend to make. The intended audience for this article is JavaScript beginners with a few years of programming experience. 

If your code is easy to read, there will be less bugs, any remaining bugs will be easier to debug and new coders will have a lower barrier to participate in your project.

For all its warts and headaches, JavaScript has emerged as the lingua franca of the modern Web, arguably second in adoption only to HTML itself, which obviously is just a markup standard rather than a full-fledged programming language. It’s effectively impossible to launch a sophisticated Web project without making extensive use of JavaScript and AJAX dynamic loading.
