4. Helpful Resources

1. Use Jasmine to TDD JavaScript code.
2. Understand basic JavaScript - functions, control structures, scope.
3. Refactor code OO JavaScript using object literals and objects created with a constructor function
4. Use jQuery to display and manipulate JavaScript Objects in the DOM.

Start your test server by running rake jasmine

Here are some features:

• A tree can age.
• For each year the tree ages up to it's fruit bearing age, it gets taller.
• After a tree reaches fruit bearing age, it can grow fruit.
• A tree grows a random amount of oranges each year it ages (after reaching fruit bearing age)
• An orange has a random diameter.
• You can pick all the fruit that grows each year.
• Any un-picked fruit dies when the tree ages again.
• A tree dies after it ages for it's max age years and can no longer bear fruit.

Here we'll be building objects with functions. In this release we will create an orange tree, age the tree, grow oranges on the tree, and pick fruit off the tree. We will model all of this using JavaScript functions and Plain-Old-JavaScript-Objects(aka Object-Literals).

• One by one, make the plain-old-js-objects-spec pass without using prototypes or constructor functions. Use the plain-old-js-objects file.
• Refactor your javascript source files!
• Refactor your spec files!

In this release we will AGAIN create an orange tree, age the tree, grow oranges on the tree, and pick fruit off the tree. We will model all of this using JavaScript constructor functions and Prototypes.

• One by one, copy the plain old js objects spec into the typed objects spec. However, change them to use the new OrangeTree and prototype syntax as you do. use the javascripts/typed-js-objects.js file.
• Refactor your javascript source files!
• Refactor your spec files!

Now let's add some interaction with the DOM. Write your DOM interaction code in view.js. Use either the objects you built in release 1 or 2.

Feel free to either write the javascript first or the tests first. It's totally up to you.

• Write a test that allows you to plant a tree by clicking a button. It should be visible on the screen somehow. Make it pass
• Write a test that allows you to pick a tree off an orange by clicking a button. Make it pass.
• Write a test that allows you to age a tree by clicking a button. Make it pass.

• Have some fun. Can you add a pear tree? Can you do it TDD?
• Can you pick all the fruit that grows each year and put it in a basket?
• Can you know the number of fruit in the basket and the average diameter of that fruit at any time?
