In future publishers will probably use web assembly for DRM, for example, to render decrypted article text on a canvas so that it cannot be copied, zoomed, read aloud or viewed without advertisement and annoying popups. Maybe you will change your mind about Javascript then.

Only they wanted to drm javascript sent to the browser. We got rid of Flash only to see a new hydra head emerge. People clamoring for javascript applications should be careful what they wish for. They just might get it.
