Hello, i didn't understand the this keyword in the below code. I know that
"The value of this, when used in a function, is the object that "owns" the
function.". However, in this code, i can't see any object. What does this
refer to in below codes?
Is Radio a function or constructor? How can we understand it?
var Radio = function(station) {
// what does this refer to?
setTimeout(function() {
// what does this refer to?
});
this.on('newListener', function(listener) {
console.log('Event Listener: ' + listener);
});
};
from the comments :
// we need to store the reference of `this` to `self`, so that we can use the
current context in the setTimeout (or any callback) functions
// using `this` in the setTimeout functions will refer to those funtions,
not the Radio class
but didn't understand
