Hello all, big noob here… 
I just purchased a 64x32 RGB LED Matrix and a RGB Matrix Bonnet for Raspberry Pi. I have a webserver (Node.js) running on a raspberry pi. The plan was to print a string that was received on the server via an API onto the matrix. I was reading rpi-rgb-led-matrix/examples-api-use at master · hzeller/rpi-rgb-led-matrix · GitHub and I don’t see JavaScript mentioned anywhere for the API.
Does this mean I won’t be able to send the data from JS, to the Matrix?
EDIT: I found this, which looks promising.
Thank you,
