Here are some of the key differences between Go and Java/Python:
Type system: Go has a static type system, which means that types are checked at compile time. Java also has a static type system, while Python has a dynamic type system.
Concurrency: Go has built-in support for concurrency, making it easy to write concurrent programs. Java also has support for concurrency, but it requires more boilerplate code. Python has a Global Interpreter Lock (GIL), which makes it difficult to write truly concurrent programs.
Compilation: Go is a compiled language, meaning that the code is compiled into machine code before it is run. Java is also a compiled language, but it uses a Just-In-Time (JIT) compiler. Python is an interpreted language, meaning that the code is executed directly by the interpreter.
Performance: Go is known for its high performance, making it a good choice for systems programming and other performance-critical applications. Java is also a high-performance language, but it can be slower to start up than Go. Python is generally slower than both Go and Java, but it is often used for rapid prototyping and scripting.
Package management: Go has a built-in package management system, which makes it easy to manage dependencies. Java also has a package management system (Maven), while Python has several package management systems (pip, conda, etc.).
Syntax: Go has a simple and concise syntax, which makes it easy to read and write. Java has a more verbose syntax, while Python has a more expressive and flexible syntax.
Overall, Go is a relatively new language that was designed specifically for systems programming and concurrent programming. It is known for its performance, simplicity, and built-in support for concurrency, making it a popular choice for building microservices, networking applications, and other performance-critical systems.
