F# includes a system of user-definable units of measure, based on Andrew Kennedy's pioneering work. The type system checks that they are used consistently and it can infer that e.g. acceleration (m/s^2) multiplied by time (s) yields velocity (m/s). However, the main benefit of all this is the type checking, so I doubt there is much value for JavaScript. If you just want dynamic checking you can build respective classes yourself.
