However, you can install any open source or licensed IDE in order to get any IntelliSense support for JavaScript and syntax error/warning highlighter. For example – Visual Studio, Aptana, Eclipse etc. Prefer an editor that has built-in features of IntelliSense support and syntax error highlighter for speedy development.
