TIOBE Programming Community Index: "JavaScript scores all time high and surpasses C#".

This makes Helma a real uber-tool amalgamating the number one and the number seven of the March index. A wider spread popularity of Helma could make JavaScript vs Python a safe bet. However, JavaScript vs Ruby remains a risky one even then.

The future is looking bright (unless she blinded me with science, ie. I guess TIOBE's methodology is arguable.)
