Modern C++ (C++11, C++14, C++17, C++20) has added many features making the language safer and more convenient. Features like smart pointers, lambda functions, and move semantics keep C++ both powerful and modern. It meets critical performance requirements for financial systems, high-frequency trading applications, and scientific computing.
6. TypeScript: The Enhanced Version of JavaScript
TypeScript is a superset language that adds static type checking to JavaScript. Developed by Microsoft, TypeScript provides type safety and better developer experience in large-scale JavaScript projects.
In modern frontend development, TypeScript has become almost standard. Besides being Angular's official language, React and Vue.js projects also commonly use TypeScript. The type system's auto-completion, refactoring support, and compile-time error catching significantly increase developer productivity.
In backend development, TypeScript used with Node.js increases code quality and maintainability. Interfaces, generics, and advanced type features provide powerful tools for safely modeling complex data structures. Excellent support in editors like VS Code makes the development experience enjoyable.
7. Go (Golang): Simplicity and Efficiency
Developed by Google, Go is a modern programming language designed for simplicity, efficiency, and concurrency. It's a popular choice for microservices, cloud infrastructure, and DevOps tools.
Go's syntax is extremely clean and minimalist. It's easy to learn but has enough features to build powerful systems. Built-in concurrency support (goroutines and channels) makes it easy to write high-performance, concurrent applications.
Popular DevOps tools like Docker, Kubernetes, and Terraform are written in Go. Fast compilation times, ability to produce static binaries, and low memory consumption make Go ideal for cloud-native applications. It's widely used in microservice architectures, API development, and system tools.
8. Rust: Safety and Performance
Rust is a systems programming language designed to provide memory safety and concurrency safety. It combines C and C++'s performance with memory safety guarantees.
Rust's most important feature is its ownership system. This system catches memory errors at compile time and guarantees memory safety without needing a runtime garbage collector. This is revolutionary in terms of both performance and security.
Rust is gaining popularity in web assembly, embedded systems, blockchain, and operating system development. Mozilla's Servo browser engine, AWS's Firecracker, and some of Discord's services are written in Rust. It's been voted most loved programming language in Stack Overflow surveys for years.
9. Kotlin: Modern Android Development
Kotlin is a modern programming language developed by JetBrains and adopted by Google as the official language for Android development. While fully compatible with Java, it enables writing shorter and safer code.
