'Where are event listeners defined in npm packages?
I've been working on coding an IRC bot in nodejs as a learning project. I've been frequently coming across event listeners such as the following:
bot.addListener("message", function(from, to, text, message) {
.
.
.
});
Problem: I've been looking everywhere for an explanation of where this addListener is defined/explained. I can't find anything. It is from the irc package in npm, and even after searching every github file in the irc package source, I find no instance of the string addListener.
What's going on here? How do I figure out how this addListener is working, what the list of IRC events are (besides just "message"), and so forth?
