What ECMAScript version is used in Max for JavaScript

By the way, I forgot to say that I am asking about Max 8

ES5.

Thank you Valery, would you also know if there is some form of console.log or some other such ability to see the this.patcher object in the Max console?

post()? (Hopefully, I understand the question correctly).

Thanks Valery, you understood correct. I just wanted to check, if you do post(this.patcher) I was expecting the object itself but instead get an id number is that the same for you? I just want to find a way to print the Javascript object so I can more easily discover its methods and properties.

For example, this.patcher.newdefault and this.patcher.newobject do similar but different things but I dont know where to find the source code or API documentation on exactly what they do and why.

Just a man trying to teach himself how to fish in the Max JS world - I am already a decent JavaScript programmer from my day job

The best place to learn Max/MSP Jitter Javascript Reference is here: http://max-javascript-reference.tim-schenk.de/#gsc.tab=0 According to documentation this.patcher.newdefault and this.patcher.newobject do exactly the same: "Create a new object of class classname in a patcher using the specified parameters and return a Maxobj that represents it."

Thank you very much Valery...really appreciate your help with my questions :)

I will check this link out

I wonder why Max JS is not getting an update to the latest ECMAScript?

cycling74.com/forums/any-plans-to-update-support-for-recent-versions-of-js#reply-58ed21d5c2991221d9ccad8c I think this is sill valid. Since Max8 has built-in Nodejs we can transpile "natively" in Max project.
