First class of the OOP course, in which we see what object-oriented programming is, its versatility and why it is convenient for us to learn.
1 – Introduction to OOP
OOP (Object-oriented Programming) or OOP (Object-oriented programming) is a new paradigm in programming, which goes one step beyond the functional language (of functions) what we learned in
Object programming was introduced in version 5 of PHP to make it much more scalable and functional. As we will see, it has many applications, and the resulting code is pure poetry. So, let’s start with the theory: What is OOP? What good can it do us? What can we do thanks to her? Let’s go there!
You see it. Objects are intelligent, self-contained entities and also have “memory”, so we can use variables and functions outside of them, unlike functions, which were limited in scope.
But also, there is no longer “everything” as such. The “great” program, but we can work with independent objects that are related to each other, and that together form an application as huge as Facebook, as we discussed in the example of the video.
And on top of that they are “reusable”, so we can simply “copy and paste” an object from one program to another, and it will work perfectly. They are like “little programs”.
Thanks to this we will be able to work as a team much better, create modular programs, reuse code, and even work with frameworks.
I mean, you already know: If you like what Luis tells you in this intro, don’t miss the next class, because the game begins. Until then… Very good morning!
Remember that if you will have access to everybody the courses and you can also enjoy everything from .
