If i am not mistaken, Object.assign is ES6 standard method rather than ES5. So, i suppose we need extendscript-es6-shim for that method, and for many others, like Object.is(), Array.prototype.findIndex() etc. Or, we can try to use Babel for that, because ES6 is not just a new methods, but a new syntax.

hm. You're right we should keep those separated.

Okay. Moved it to a new repo https://github.com/ExtendScript/extendscript-es6-shim
