Document required ECMAscript version #911

Open fhammerschmidt opened 1 month ago

I don't think we have documented the requirements on the JS version / spec at the moment.

Starting with v12, ES6 (ECMAScript 2015) is required because we are now making use of the following ES6 features:

let keyword
arrow functions
spread operator

Document for both:

[ ] v11 is mostly es5 (some stdlib functions may already have been es6)
[ ] v12 is just es6
