OOP

Getting started with OOP in Magento 2 requires some knowledge of the language and its architecture. This quick start guide will provide the basics of OOP and provide step-by-step guidance on the different concepts and techniques of the language. Moreover, it will also give an overview of the many extensions and themes available for Magento 2.
Dependency Injection

One of the most important advantages of using Dependency Injection in Magento 2 development is its compatibility with the Object Manager. The Object Manager can introduce compatibility issues as it skips type validation checks. DI is similar to Composer in that it enables you to specify packages without requiring them to be packaged. It is useful in cases when your reliance changes on every strategy call. The Magento Framework EventObserver class is an example of a dependency that is best handled through DI.
ViewModel

This section introduces the new concept of ViewModel in the Magento 2 development framework. ViewModels represent data used for rendering. They include data lookups, object fetches, and calculation logic. They are used instead of blocks and make the code less complex and more maintainable. They provide a simplified method of customizing the UI of your website. In this article, we’ll explore the advantages and disadvantages of this new concept.
Composer
