What type of data is used to store a stack in a goroutine: static or dynamic?

In Go (Golang), a goroutine's stack is implemented as a dynamically sized structure. Initially, each goroutine is allocated a small stack (usually around 2 KB), which can automatically grow or shrink during program execution depending on the needs.

This allows for efficient memory usage and the ability to run a large number of goroutines without significant resource costs.

Therefore, a goroutine's stack is not a fixed static size but is dynamically managed by the Go runtime.
