Object-Oriented Programming (OOP) is an important paradigm in programming. It is the concept of using classes and objects to model the real world. Learn what are classes, how to reuse and inherit class functionality. Classes and objects are the building blocks of object-oriented programming (OOP) and they come together with some other OOP concepts like abstraction, interfaces, data encapsulation, inheritance, polymorphism, and exception handling.

Have you ever wondered whether you need to be good at math to become a developer? Well in this video we explain it all.
Developers don’t need to prove theorems or solve differential equations, but they need to understand coordinate systems, they need to know what a function is, they should be able to perform simple calculations, and they should have well-developed algorithmic thinking, which is like the logical thinking used in math.

Functional programming is a programming paradigm where programs are constructed by applying and composing functions. It is declarative rather than imperative, and the application state flows through pure functions. Functional code tends to be more predictable and easier to test than imperative or object-oriented code — but if you’re unfamiliar with it and the common patterns associated with it, functional code can also seem a lot denser.
Learn which of the programming languages are functional.

Unit tests are pieces of code that test specific functionality in a certain software component. Usually, they aren’t written by QA engineers but by developers as part of the product source code that aims to improve its quality, reliability, and maintainability.
Unit testing is commonly automated but may still be performed manually. I show an example in JavaScript, but the concepts are applicable for any programming language.

Source control management (SCM) systems are widely used among software developers. SCM systems help you collaborate on code with your team, isolate your work until it is ready, and quickly troubleshoot issues by identifying who made which changes and keeping a history of every single piece of code that is committed.
In this tutorial, we’ll look at Git and GitHub. Git is an open-source distributed source code management system. It allows you to make a copy of your repository known as a branch. By creating this branch, you can work on your code independently from the stable version of your codebase.
I’ll also show you how to make a portfolio of your projects on GitHub to help you start your first developer job.

Become a Java Certified Developer!

In this Java series, you will acquire all the needed skills to become a Java-certified developer. By now you’ve learned all about arrays, but did you know there are more data structures in programming? Lists are one of the most popular data structures in programming, as they allow for flexibility. You can insert and delete elements at any point and their length is not fixed! Cool, right?

In this video we learn the commutative property of addition and multiplication. The commutative property tells us that it doesn't matter which order we add or multiply in. We can right this rule like this:

a + b = b + a
ab = ba


Although this rule is very simple its very important!

This video talks about the mechanism involved in an SN1 reaction. It also elaborates on what is a rate determining step and how it affects the rate of a reaction. We learn how to calculate the rate of an SN1 reaction and also, what is the order of an SN1 reaction. In the end, it tells why the nucleophile does not affect the rate of an SN1 reaction while the concentration and type of substrate does.

Windows Forms is a classic software framework for the development of Desktop graphical user interface (GUI) apps for Microsoft Windows. It is based on the .NET platform and the C# language and provides a programming model and rich UI control library for building GUI apps. Additionally, the Visual Studio IDE is a powerful visual UI builder for Windows Forms, where developers design the user interface by dragging and dropping UI controls and configuring their properties and events.

In short, React.JS is a component-based front-end technology for the Web. The JSX components in React combine HTML and JavaScript to display the component UI, which is bound to the internal component state.
It is debatable whether React is a library or a framework. It is maybe somewhere in between.
By adding some additional components like React Router, MobX, Redux, Flux, React Toolbox, and some others, we can turn React into a fully-functional Web front-end framework.

In a nutshell, the Internet of Things is the concept of connecting any device (so long as it has an on/off switch) to the Internet and to other connected devices. The IoT is a giant network of connected things and people – all of which collect and share data about the way they are used and about the environment around them.
In this dev lesson let’s look into the basic principles of IoT and IoT microcontrollers. I also have an example prepared in TinkerCad so you can see the concepts in practice.

Quality assurance, or QA Testing, is used to measure the quality of software. It focuses on improving the software development process and making it efficient and effective as per the quality standards defined for software products. QA includes creating processes for each stage of the project for reducing bugs and flaws during the build.
In this Dev Concepts lesson, I explain more about the principles of QA and have a live demonstration to show them to you in action.

Software engineering is an engineering branch associated with the development of software products using scientific principles, well-known methodology, and procedures. The outcome of software engineering is an efficient and reliable software product. In this overview video, I'll review the most important topics in software engineering. We will talk about SDLC, QA, Unit Testing, Git and GitHub, and some Project Tracking Tools. To illustrate this better each of these topics contains a small demo.

In Java exceptions are objects. The base for all exceptions is the Throwable class – it contains information about the cause of the exception, its description, and the stack trace. To raise an exception, you use the throw keyword. When an exception is thrown the program execution stops, and the execution travels over the stack until a matching catch block is reached to handle it.
Learn what are the main methods for exception handling and how to simplify your code construction.

This is a more advanced example of using the chain rule. In this video we need to use the chain rule twice in a row in order to find the complete derivative. Don't let the title fool you, its not difficult, its just a more advanced example that you should know how to do!

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
