While you can run Javascript on any hardware, you won't be able to reuse common JavaScript VMs (wether be it V8, JavaScriptCore or Mozilla's engine) on a Cortex-M CPU. The main limitations are: * Thumb/Thumb2 only, though JavaScriptCore does generate Thumb2. * no mmu so no fully featured OS such as Linux and this is a show stopper. * very limited RAM, measured in KiB! So you need VM targeting this class of CPU. I have heard of some but I doubt they support the full ECMA specs.
An option may be to look at entry level boards with Cortex-A CPU such as the beaglebone black: Cortex-A8, 512MiB RAM, 45$. Not as cheap as an M but it would run all the VM quoted earlier.
