Golang’s stack is in memory and is mainly used for temporary storage during function calls. When the function is called, the parameters of the function and other local data are pushed into the stack. When the function returns, these data And popped from the stack, so the stack provides a convenient way to manage data during function calls.

Golang’s stack is in memory and is mainly used for temporary storage during function calls.
When a function is called, the function parameters and other local data are pushed onto the stack; when the function returns, these data are popped out of the stack. Therefore, the stack provides a convenient way to manage data during function calls.
#When a variable is declared as a local variable of a function, it is usually allocated on the stack. Each thread has its own stack, and the size of the stack can be controlled by setting runtime.Stacksize.
In Golang, the implementation of the stack is based on linked lists. Each stack frame consists of the following three parts:
Data: the data stored in the stack
Pointer: points to the function that is called Stack frame
Control information: contains function return address and other information related to function call.
When a new function is called, a new stack frame is created and pushed onto the stack. When the function returns, the stack frame at the top of the stack is popped and control is returned to the caller. This stack-based calling model makes recursive calls possible and allows Golang to support advanced programming concepts such as coroutines.
In short, Golang’s stack is very important for function calls and provides a convenient way to temporarily store data during function calls. The stack is implemented using linked-list-based stack frames to support advanced programming concepts and allow control to be passed through the stack between functions.
