What are the differences in concurrency models across programming languages?

What are the differences in concurrency models across programming languages?

Different programming languages implement concurrency in various ways. For example, Java uses threads and the Executor framework, while JavaScript uses an event loop and callbacks.

Can you explain how Python handles concurrency?

Python primarily uses threading and multiprocessing. The Global Interpreter Lock (GIL) can limit the effectiveness of threads, so multiprocessing is often preferred for CPU-bound tasks.

What about Go? How does it manage concurrency?

Go uses goroutines, which are lightweight threads managed by the Go runtime. It also has channels for communication between goroutines, making concurrency easier to handle.

Are there any languages that use a different approach?

Yes, languages like Erlang use the Actor model, where each actor is a concurrent entity that communicates via message passing, providing a different paradigm for concurrency.
