  Introduction to Scala

  | 236 students

  The name Scala derives from a combination of the words “scalable” and “language”. Scala is a functional programming language, which runs on top of the Java virtual machine and can use any Java class. Scala is well suited for distributed programming and big data. It is what Apache Spark is built in and can provide better performance when compared to Python and is much less verbose than Java. Whether you’re learning about functional programming or starting a career in big data, Scala is a great place to start.

  Object-Oriented Python

  | 5400 students

  Sometimes simple scripts with functions in them just aren't enough. Eventually you'll need logical models of your work and that'll lead you to creating custom classes in Python. Object-oriented programming is a large topic. It provides us some amazing tools, though, so it's one of the most beneficial things to learn about in Python. First, you'll learn how to build basic custom classes. Then, you'll expand them through inheritance. And for some extra power, you'll also learn how to take control of Python's built-in classes to make your own more powerful while doing less work. Finally, we'll put everything together into a fun game utility.

  Object-Oriented PHP Basics

  | 2828 students

  At a glance, object-oriented programming can appear to be far more complex than simple procedural, or inline, code. However, this doesn’t have to be the case. Because object-oriented programing is similar to the way human beings perceive the real world, using the object-oriented approach, can help you visualize the solution to a problem more easily. Object-oriented programming, or OOP for short, is a style of coding that allows developers to group similar tasks into containers. In PHP, containers are defined using classes. A class contains all the functions and variables that describe an object.
