Edit Question
Title
Body
I'm just getting into JavaScript and I'm trying to wrap my head around prototypal inheritance. It appears that there's multiple ways to achieve the same effect, so I wanted to see if there is any best practices or reasons to do things one way over the other. Here's what I'm talking about: // Method 1 function Rabbit() { this.name = "Hoppy"; this.hop = function() { console.log("I am hopping!"); } } // Method 2 function Rabbit() {} Rabbit.prototype = { name: "Hoppy", hop: function() { console.log("I am hopping!"); } } // Method 3 function Rabbit() { this.name = "Hoppy"; } Rabbit.prototype.hop = function() { console.log("I am hopping!"); } // Testing code (each method tested with others commented out) var rabbit = new Rabbit(); console.log("rabbit.name = " + rabbit.name); rabbit.hop(); All of these appear to have the same effect individually (unless I'm missing something). So is one method preferred over the other? How do you do it?
