1. Object-oriented programming

Object Pascal supports object-oriented programming (OOP). Developers can use classes, inheritance, polymorphism, and other OOP concepts to write clean and highly maintainable code.

2. Simple syntax

The syntax of Object Pascal is clear and understandable.
This makes programming easier and much more safe.

3. Stability, maturity and modern

Stability and maturity
Object Pascal has a long history and was developed with Turbo Pascal in the 1980s. The language has proven itself over time and is stable and reliable.
And yet Object Pascal is very modern: Free Pascal and the Lazarus IDE are constantly being developed. The current version of the Lazarus IDE is 3.4, released on May 29, 2024. The Free Pascal compiler is version 3.2.2, released on June 14, 2021. Both are constantly being developed.

4. Performance

Object Pascal is implemented in Free Pascal. And Free Pascal offers very good performance with efficient machine code. This is especially important for applications that have high speed requirements.

5. Platform independence

Object Pascal is implemented in Free Pascal. Free Pascal is a cross-platform programming language that works on various operating systems such as Linux, macOS, Windows, and much more operating systems.

6. Libraries and Frameworks

There are a variety of libraries and frameworks for Object Pascal that make development easier. Examples include the Lazarus IDE, the FCL library (for cross-platform applications), and the VCL library (for Windows applications).

7. Community and resources

There is an active community of Object Pascal developers who support each other, and there are many tutorials, forums and books to help with development.

8. Integration with other languages

Free Pascal can interact with other languages ​​such as C and C++. This allows the use of existing code or the integration of specific functions.

9. Versatility

Object Pascal is suitable for a wide range of applications, from desktop applications to game development to embedded systems.

10. Open source

Free Pascal is free and open source. Developers can use the language without license costs and adapt the source code.
