The key to understanding when (and when not) to deploy JavaScript has as much to do with the intent of the target application as it does JavaScript itself.

JavaScript is now the world's most popular programming language, even though it started off as a side-kick to Java.

Sentry announced it now provides a full suite of application monitoring capabilities for JavaScript developers.
