JavaScript callbacks and events

Question

For one of my lecture at university we are learning about callbacks, I half understand what they are but the question I have is where can you find the events for elements.

load in:

img1.addEventListener(’load’, function() {
// woo yey image loaded
});

yay in:

some_function("yay", function(value) {
console.log("callback called! " + value);
});
