In the Go language, the storage area of variables is determined at several stages of the program's lifecycle:

1. Compilation

   • The compiler analyzes the code and determines where and how variables will be stored: in the stack, in the heap, or in static memory.
   • Local level variables are usually placed on the function's stack.
   • If a variable is captured by a closure or its address is passed outside the function, the compiler may "lift" it to the heap (escape analysis).

2. Runtime

   • When a function is called, a stack is allocated for local variables.
   • For variables stored on the heap, memory is allocated dynamically.

3. Initialization

   • Variables are initialized with default or specified values.

Thus, the determination of the variable storage area occurs at the compilation stage (through code analysis and escape analysis) and is implemented at runtime by allocating memory on the stack or heap.
