setTimeout callback argument

Question

Let\'s consider this piece of JavaScript:

function Person(name) {
    this.name = name;
}

Person.prototype.showName = function() {
    alert(this.name);
}

         


        

Answer 1

If the accepted answer is just too long to read:

setTimeout(mike.showName(), 5000);

This will execute whatever mike.showName() returns after 5,000 milliseconds.

setTimeout(function(){ mike.showName(); }, 5000);

This will execute anonymous function after 5000 milliseconds that calls mike.showName() , the actual function.

Another way to achieve same effect:

setTimeout(mike.showName.bind(mike), 5000);
