I like working with data. As a graphic designer structured information is like M&Ms to a three year old. Sort all the colours! The lesson I just completed dealt with objects, classes and prototypes and explained inheritance. Being familiar with CSS inheritance and classes were ringing a solid brass bell. Basic inheritance looks something like this:
Yes, these can be confused with objects. It's Monday morning and I'm exhausted. It's a great time to learn and absorb new information... well, maybe not. But here we go. My coffee is standing here getting cold and I'm reaching to the depths of my memory to remember things I learned a week ago. I need sleep, but let's continue.
If we don't know what whether we're working with a string, number, boolean or object we can use the typeof command. Nifty.
I found myself asking this question because the two seem painfully similar. I found the following answer at Stackoverflow, Andrew Edgecombe explains
A function is a piece of code that is called by name. It can be passed data to operate on (i.e. the parameters) and can optionally return data (the return value).
All data that is passed to a function is explicitly passed.
In the latest lesson we looked at dealing with objects as an array, in the specific example we had a family array containing members of the family with their respective details. We constructed objects using the object constructor and then ran a couple of functions on that object.
The following is my practice code using fictional rocket ships as objects. First we'll create a set of rockets ships with all their details. Then we'll compare them to see which is the fastest.
I really blew the last assignment. Here's what I did, and how I changed up my code until I got it to work. I probably need to spend some more time creating exercises like this to really get this stuff in my head.
The assignment: Create 3 rabbit objects with adjective key values of fluffy, happy and sleepy. Easy, right?
Using the tools from previous lessons, specifically the object constructor and method I wrote this short piece to provide information on a specified book and calculate reading time based on the user's wpm.
The object constructor allows us to use a function to build objects from structured data. At first glance it looks almost like a CSV import function.
Objects are made up of three basic pieces. The object, its properties and their values.
var myObject = {
property1: value1;
property2: value2;
property3: value3;
etc...
}
Looks like we'll be working with some objects in the next lesson, so I'm going to go ahead and create one here:
It's all nice and dandy that I've heard this term before and can even sorta figure out what it means, but what does it really mean?
The top results in Google for OOP comes from TechTarget.com. It reads:
Object-oriented programming (OOP) is a programming language model organized around objects rather than "actions" and data rather than logic. Historically, a program has been viewed as a logical procedure that takes input data, processes it, and produces output data.
