Completely agree. Declarative approaches define the palette of available options ahead of time, but if wish to do something out-of-scope, it's back to the drawing board. Imperative approaches instead give you a low-level computation environment, and hooks into manipulating the outside world. Most facets of the original Web are declarative: HTTP is a complex state machine, HTML is a declarative language, hyperlinks are declarative ways of specifying outgoing edges of a node in a graph. Javascript enhanced that with imperativeness, which is why it's been leveraged to extend the Web in new ways -- ways that are ad-hoc reimplementations of behaviors that have not (yet) been otherwise codified.
