 ## Introduction
 
-We are excited to announce the launch **Radon** - a new open source programming language for the modern world. The language is designed to be simple, fast, and safe while incorporating modern language features such as type inference, pattern matching, and more. A key goal of the language is to be easy to learn and use, while still being powerful enough to build complex applications. It is also designed to be easy to embed in other applications, and to be used as a scripting language. The language is currently in the early stages of development, and we are looking for contributors to help us build the language.

 ## Object Oriented Programming
 
-Object Oriented Programming (OOP) is a programming paradigm that uses objects and their interactions to design and program applications. It is based on the concept of objects rather than just functions and procedures. These objects are organized into classes, which allow individual objects to be grouped together. Most modern programming languages including Java, C/C++, and Python are object-oriented languages, and many older programming languages now have object-oriented versions.

They are declared using the `var` keyword. It is followed by the name of the field and the type of the field. The type of the field is optional.
