Pro Provides quick fixes
Eclipse with JSDT provides you with quick fixes every time a warning or error is raised by the IDE. This feature is particularly helpful at places in code where errors were caused by the programmer just being a little "lazy", such as missing out the

Just like all other IDEs, Eclipse offers you inline code completion (even with any external JS libraries added to the project).
Pro Free and cross-platform
