Is golang multi-threaded or single-threaded?

Golang is a multi-threaded language. It uses lightweight coroutines as concurrency primitives and can take full advantage of multi-core CPUs. Coroutines are managed by the Go scheduler, which is responsible for allocating CPU time slices and coordinating coroutine execution.

Is Golang multi-threaded or single-threaded?

Golang is multi-threaded.

Detailed explanation:

Golang uses a concurrency primitive called goroutine. Coroutines are user space threads, which are executed in user mode and are different from operating system kernel threads. Coroutines are lightweight and can be easily created and managed without incurring significant overhead.

Through coroutines, Golang programs can perform multiple tasks at the same time, thereby taking full advantage of multi-core CPUs. Coroutines are managed by the Go scheduler, which is responsible for allocating CPU time slices to coroutines and coordinating their execution.

Although Golang supports multi-threading, it is generally more suitable to use coroutines for concurrent programming. Coroutines are low overhead to create and manage, and can be easily used with other concurrency primitives in the Go ecosystem, such as channels and mutexes.
