Why Do Go Applications Need a Runtime if They are Compiled?

Why Go Applications Require Runtime Support

Despite being a compiled language, Go applications necessitate runtime assistance. This is due to specific characteristics of the language:

Platform Independence: Go binaries, unlike many other compiled languages', can run on any platform supported by the Go runtime. Instead of generating platform-specific instructions, the Go compiler converts the source code into an intermediate representation that the Go runtime executes.

Garbage Collection: Go employs automatic garbage collection, eliminating the need for programmers to manually manage memory allocation. The runtime manages the allocation and deallocation of memory, optimizing memory usage and preventing memory leaks.

Goroutines and Scheduling: Go supports concurrency through goroutines, lightweight processes that execute concurrently. The runtime handles scheduling, context switching, and synchronizing access to shared resources, enabling efficient and scalable concurrent programming.

Higher-Order Functions and Functional Programming: Go incorporates functional programming elements such as closures and higher-order functions. The runtime supports these features, allowing programmers to write concise and expressive code.

In conclusion, Go applications require runtime support due to their platform independence, garbage collection, concurrency features, and support for functional programming. While Go binaries can be distributed across platforms, the runtime remains essential for executing the intermediate representation, managing memory, and enabling concurrency.
