PharoJS V22 is available on SmalltalkHub.
From the release notes: RELEASE V22 Added statistics package. Generates statistics about Pharo classes used by an app and the size of generated JS code
Fixed default app folder parent to fit the modification in github repo = non-pharo code moved to HTML folder
This is like the last version done on Pharo 5 and SmalltalkHub as Noury will switch to GitHub now.
