Why wouldn't we want the same thing for JavaScript? I think the question is whether you want _more_ than that for JavaScript. For images, you can preload them and choose when they're shown, but _cannot_ choose when they're decoded. For CSS, you can preload it and choose when it's applied but _cannot_ generally choose when it's parsed. For JS, you want to be able to preload it and control when it's executed (in the sense that the side-effects it causes become visible). The question is whether control is also needed over exactly when side-effect-free preprocessing of the script happens. -Boris
