87 points · Open discussionModdable and Espruino have a slightly more restrictive license for when u want to maybe monetize your project.
Duktape and Jerryscript are way bigger open-source projects (on github at least). I used almost all of the interpreters to do a hello world on a microcontroller. They all work great! I found Duk to have a slightly cleaner API for bindings, for example writing to the serial port from JS land.

In Espruino: JavaScript for MicrocontrollersThere's at least two years of work in there as Fabrice Bellard's side project. This would mean about ~10-15 man-years of full-time work for a small team of experienced engineers, which is about what it took for jerryscript:
https://github.com/jerryscript-project/jerryscript
Granted, the targets aren't exactly the same (micro-controllers vs very small lib), but benchmark differences are impressive:

In QuickJS JavaScript EngineCheck out http://duktape.org. Extremely easy to embed, great performance, and can go down to a ridiculous 1.5KB of RAM at startup.
This and JerryScript (https://github.com/jerryscript-project/jerryscript) are the two most active embedded JS engines.

3 points · Open discussionWait, so Samsung wrote their own new JavaScript engine for embedded devices? This is actually very cool.
It looks very constrained in what it supports so far though.
Update: They're at ECMAScript 5.1 https://github.com/Samsung/jerryscript/issues/205 but not all tests are running https://github.com/Samsung/jerryscript/issues/158
Ok, it doesn't yet JSON.stringify https://github.com/Samsung/jerryscript/issues/432 so not sure if ready yet.
