Effectively working with arrays is critical to any JavaScript programmer. Arrays are an important data structure, and this course will provide you with the competency you need to master them.
In this course you are going to learn all there is to know about JavaScript arrays. I start from the beginning, so if you are comfortable with JavaScript, you may want to use the first section as a review or skip it. You will learn the basics of different ways to create an array and work with the elements. You will learn the basics of iterating an array and some unique ways to create arrays and access elements. You will learn all the methods to modify or mutate an array, as well as those methods that are preferred in the functional programming world because they preserve the original array. You will learn how to combine arrays and extract values as well as multiple ways to search arrays for values. We will end with a look at some array-like collections available in JavaScript and how you can use those.
By taking this course:
  • You will feel more comfortable working with arrays in any coding problem you encounter.

Instructor Details

Steven Hancock

I have had 20+ years experience in training and product development and 15+ years working with JavaScript. I started learning JavaScript when it was a new language used for minor affects on a web site. The growth and ubiquitous nature of JavaScript both excites and inspires me.
I currently work as the President and Lead Trainer at All Things JavaScript, a resource for anyone and everyone that hopes to increase their JavaScript skills and move from novice to expert.
I'm doing what I love most: Teaching about technical subjects. It is so important to understand the why, not just the what and how, when it comes to technical subjects. My goal is to help thousands of JavaScript developers to get started and become experts in the field making a great living coding.
I was the co-owner and President of Rapid Intake, an eLearning firm. The company was an ideal place for me to apply my training and development skills. While there I managed all development and professional service related activities. I was heavily involved in the initial development of Rapid Intake's main product, an eLearning authoring tool, which eventually lead to Rapid Intake's acquisition in 2011 by Callidus Software.
In addition to JavaScript technologies, I have dabbled in other web technologies such as ActionScript, ASP, PHP, HTML, and CSS.

Excellent, excellent course. Steven is by far the best JS instructor around. His knowledge is profound, and he possesses the rare skill to transmit it easily... I only wish he would show how to build a full fledged app. But yet the learning experience one gets from his courses is priceless!

One of the best courses I've purchased.
