Just Methodical Penguins

     Coffee! It happened! Olé! I've been making it a habit to not go to the coffee shop during the week and have a French press at home when I need the caffeine. However, getting out of the house on occasion is good for me. That's why I come to the coffee shop on Friday. It's good for everyone. I don't scare people/ get ridiculed because of my beard, I save money, I get to sleep longer, win-win really. I wear my +Jupiter Broadcasting  sweatshirt, (which will soon have a  matching shirt(whoo!)) and get things done! I've got a salad waiting for me when I need a break, I've had my coffee, I have Grooveshark (again. Such a creature of habit.) playing a Piano Guys playlist because I love the cellos and piano together, so it's time to plug in and plug away!


But first, a link: https://developer.mozilla.org Seriously, it's just a good place to go when you need some info on . js, HTML, CSS, and of course Firefox and all those things that they do. Also, Persona. Seriously. Sign up, get the newsletter, it's just a good idea.

HTML/CSS

      So, (again)there isn't much to report on this front. Mainly I'm getting through things and reading a lot of the stuff on Mozilla. So, if you want some HTML for today, head over there and check out some of that stuff. It's always a good idea.

JavaScript

      Now onto methods. Yup. Moar methods! This time it's something that helps us with a lot of things. It's such a long list, just go here and they'll tell you everything. Here's an example of prototype with penguins!


// create a Penguin constructor here
function Penguin(name, numLegs){
    this.name = name;
    this.numLegs = numLegs;
}

// create a sayName method for Penguins here
Penguin.prototype.sayName = function(){
    console.log("Hi my name is " + this.name);
};

// our test code
var theCaptain = new Penguin("Captain Cook", 2);
theCaptain.sayName();

And that means that we can create as many penguins as we want! You can also inherit from another Method so that you only need to add to something instead of creating an entirely new one. Example:

// the original Animal class and sayName method
function Animal(name, numLegs) {
    this.name = name;
    this.numLegs = numLegs;
}
Animal.prototype.sayName = function() {
    console.log("Hi my name is " + this.name);
};

// define a Penguin class
function Pengiun(name){
    this.name= name;
    this.numLegs = 2;
}

// set its prototype to be a new instance of Animal
Penguin.prototype = new Animal();
var tux = new Penguin("Tux");
console.log(tux);

     Notice on the first one that we had to say how many legs it had, but on the second one, we just have the name as a parameter, and the legs are always going to be two, because; well, penguins only have two legs. Unless they lost one to a seal, or something. We can also call tux with <sayName> and it'll do the whole script. Do this:

tux.sayName();

and you get this:

"Hi my name is Tux"

 The reason that happens is because we added it as a new Animal et voila! It does the magic.

     As an aside, this section was so full of bugs it that I am seriously going to need a walk. They just ignore the needs of their students and don't give a <censored> about anything. I'm just glad I'm almost done with them. At least in the .js and HTML area. That'll about for me folks. Don't forget to check out the Mozilla stuff. Seriously, tons of cool stuff over there. See y'all on Monday! If the lessons aren't TOO buggy, I should be celebrating the end of the course!
