Programming WebRTC: audio feature function uses wrong selector
In P1.0 of the book (I’m reading on Kindle so not sure what page number), the “Sharing Features over Data Channels section”
has this code:
const status = document.querySelector(’#videos #status’);
the correct selector should be (‘#mic-status’), since this is for audio.
