Javascript 'this' versus object name
javascript, object, this
Solution
The difference becomes obvious, if you have a look at this example. It creates a second object and sets the prototype accordingly.
var user = {
name : 'John Doe',
show_name : function(){
alert(this.name);
// OR
alert(user.name);
}
};
user2 = Object.create( user );
user2.name = "someone else";
user2.show_name();
Here `this.name` refers to the current object's `name` property, whereas `user.name` always refers to the original `name` property.
Problem
A question spurred by curiosity, if I have the following code, what's the benefit (beyond just the simplicity) of calling a property via `this` instead of `user` in the `show_name` method? ``` var user = { name : 'John Doe', show_name : function(){ alert(this.name); // OR alert(user.name); } }; ```
