It is possible to enable a code editor helpers for .js files in Visual Studio 2010.
I am tasked to alter the existing JavaSript files, and I am having a hard time to even getting around the written codes, since VS editor treats JS as text. I think Notepad++ would do a better job in this case.
Consider a simple example in the image below:

When an opening braces are selected, the closing ones should also be highlighted so see the boundaries of the function.
The question is: Is there an extension, or some other add-in to VS to enable comfort javascript editing?
JScript Editor Extensions looks good
