^^ this. I've been trying to phrase it for a while now. Well put. It's useful to remember that JavaScript engines are not the only consumers of JavaScript source code. Linters, transpilers, syntax highlighters, code introspection and refactoring tools, etc., etc., etc. -- they all have their cages rattled by syntax changes. The more complex the syntax (and this would have to be quite complex in a world of class fields, private data, etc.), the more the cages are rattled. Humans, too, are consumers of JavaScript source code. We're clever, but adding to the cognitive load needs a good justification. For me, the cost/benefit on this optional commas thing is just nowhere near a sell. -- T.J. Crowder
