Is automatic context switching between goroutines mandatory in Go?

In Go, automatic context switching between goroutines occurs, but not in the classic sense of preemptive multitasking as in operating systems.

Goroutines are lightweight threads managed by the Go runtime. The Go scheduler switches execution between goroutines to efficiently utilize system threads.

Features:

• The Go scheduler uses cooperative multitasking: a goroutine must yield control, for example, when calling blocking operations or functions that explicitly yield.
• Since Go 1.14, limited support for preemption has been added, allowing the scheduler to interrupt a goroutine if it does not yield control for a long time.

Thus, context switching between goroutines happens automatically and transparently for the developer, but with some features that differ from a classic OS.
