Woohoo, excited about this, thank you @tirtawr! I think this pull request needs to be made to development rather than release!

[tirtawr]

@shiffman oops, my bad. I've updated the target branch.

@loaiabdalslam Hmm, yeah I'm not sure about this. I was just following the examples that were already there 😅. Maybe @joeyklee knows more about this? It might be because currently for these specific examples we're using an unreleased version of ml5 that's still in the development branch.

[shiffman]

@tirtawr that's correct! In the development branch, the ml5 library points to a locally built file (which assumes you are building your own dev version of the library), the release examples point to the actual release! @loaiabdalslam

Many thanks @tirtawr ! Merged! 🙏
