Q39. Is there anything for JavaScript developers?
A. Yes. We recently released JavaScript Editor extensions for VS 2010. These are few highly demanded features by developers and we couldn’t wait for long to have them out there. The Key features that these extensions contain are:
- Brace Matching – Matches {}, (), [] in your code to easily navigate through files
- Outlining/Code-Folding - Adds support for automatically creating outlining regions for JavaScript blocks.
- Current Word Highlighting – Like C#/VB editors now JavaScript Editor now will also highlights usage of the current word (based on cursor position) throughout the document for improved readability
- IntelliSense Doc-Comment <para> support – In earlier versions you might have seen tremendously long never breaking lines of comments pop up as tool tips when you typed. This was because we did not have any way to determine line breaks for xml comments. With support of <para> elements in XML doc comments this becomes immensely more usable.
You can get all these extensions from VS Extensions Gallery
After you have installed the extensions you can also get the updated vsdoc files for jQuery with <para> tags which are available at jQuery 1.4.3 and 1.4.4
