Rust is a modern systems programming language developed by the Mozilla Corporation. It is intended to be a language for highly concurrent and highly secure systems. It compiles to native code; hence, it is blazingly fast like C and C++. This tutorial adopts a simple and practical approach to describe the concepts of Rust programming. This tutorial has been prepared for beginners to help them understand the basic and advanced concepts of Rust. Application programming languages like Java/C# are used to build software, which provide services to the user directly. They help us build business applications like spreadsheets, word processors, web applications or mobile applications. Systems programming languages like C/C++ are used to build software and software platforms. They can be used to build operating systems, game engines, compilers, etc. These programming languages require a great degree of hardware interaction. Systems and application programming languages face two major problems − - It is difficult to write secure code. - It is difficult to write multi-threaded code. The Rust language was designed for developing highly reliable and fast software in a simple way. Rust can be used to write high-level programs down to hardware-specific programs. Content in this App: - Learn rust programming beginners to advance guide - Rocket - Actix - Tide - Chrono - Rand - Hyper - PostgreSQL - MySQL

Kadmia – Learn JavaScript With Games Kadmia helps you learn JavaScript by *doing*, not just watching tutorials. Most coding apps focus on passive learning—videos, long explanations, and memorization. Kadmia takes a different approach. Through interactive challenges and games, you actively build your programming intuition step by step. ### Build a Real Foundation Great programmers aren’t made by memorizing syntax. They’re built on strong fundamentals. Kadmia focuses on **first principles** of programming: * Variables and logic * Functions and flow * Problem solving * How code actually works Each concept builds naturally on the previous one, helping you develop skills that compound over time. ### Learn Through Play: Tap the Bug Our signature game, **Tap the Bug**, turns debugging into an engaging challenge. Bugs appear in your code and it's your job to spot and fix them. As you progress, the puzzles become more sophisticated—training your brain to recognize patterns and think like a programmer. It’s fast, fun, and surprisingly addictive. ### Active Learning Beats Passive Watching Instead of endless videos, Kadmia keeps you engaged with: * Interactive coding puzzles * Immediate feedback * Short learning loops * Practice that reinforces real understanding You learn faster because you’re constantly **thinking, experimenting, and solving problems.** ### Designed for Gradual Mastery Programming skill grows through consistent practice. Kadmia is designed for **daily progress**, helping you steadily expand your abilities over time. Whether you're starting from zero or strengthening your fundamentals, Kadmia helps you build the mindset and skills of a real JavaScript developer. Start learning JavaScript the way it was meant to be learned: **actively, playfully, and from first principles.**
