Absolutely agree with this.
A template based language is a new syntax for no reason except to not use JS. Learning JS is easier than learning some idiosyncrasies of templating languages.
Otto Rask I try to work with people who do know JS. Also, have some faith in the capabilities of the people you work with. JS is not hard to pick up and people with less JS skills often just copy/paste from code that is similar and already in your project.
