Using this keyword
By using just "name" it will call the global "name" as opposed to the local name
var name = "robert";
var a = {
name: "John",
greet: function(){
console.log('My name is '+ name);
}
};
a.greet();
-- Output Robert
By using the this.name it will call the variable thats associated with the a.
var name = "robert";
var a = {
name: "John",
greet: function(){
console.log('My name is '+ this.name);
}
};
a.greet();
-- Output John
