Blockly is intended for use by software developers (rather than children learning to code) to generate Javascript:
Blockly was influenced by App Inventor, which in turn was influenced by Scratch, which in turn was influenced by StarLogo. As a result, children who are familiar with one have no difficulty moving to another.

Actually, it can output Javascript, Python and Dart programs too 🙂

MIT App Inventor Usage Surpasses 100,000 weekly – Google Docs.
Usage is climbing sharply! MIT suggests the usage trend indicates high usage in schools – with a drop in the summer and a very rapid expansion once school resumed in September.
This tutorial covers the simple changing of the color of a button, while the app is running. You may also set a component’s color by changing the color properties on the Properties list in the Designer.
A second tutorial will show how to implement the continuously changing color demonstrated in the video example. That will be posted next!

To demonstrate the “simple” version, create an app with this user interface:

I have made a minor change to how posts now appear on this web site. Longer posts – especially the tutorial type posts – will show only their introductory text and images. Click on the “Continue reading–” link that appears below the post to read the full text.
By shortening the text that appears on the main page, page loads will be faster. Plus, more “short posts” can appear on the main page, making it easier to review recent content, quickly.
This change also creates a more accurate count of the posts that readers find interesting, helping to to identify the type of tutorials and content that readers want to see. Previously, full length posts, read on the main page, were not counted on the popular posts list.
Within about 2 months of starting to ramp up content on this web site, we are now seeing about 200 unique visitors each day, many arriving after searching for “how to” information using Google or other web search.
Please share these posts with your friends, using the easy social media sharing buttons that appear at the bottom of every post. Like us on Facebook, Google+ and Twitter or follow the RSS feed. Thanks!
