Thanks for that. I was aware of TypeScript but not looked at it in any detail yet. I would be interested in knowing what programming IDE you use with TypeScript and any advise on organising “Processing / TypeScript / Library development” environment would be appreciated.

As to Pjs, I used it quite a lot when applets went the way of the dodo 🥲
