Kas on Escape analüüs ja kuidas see töötab mälu haldamisel programmeerimises?

Escape analysis is a process in compilers (for example, in Go) that determines exactly where in memory an object should be stored: on the stack or on the heap.

If an object "does not escape" from a function (i.e., it does not "escape" it), then it can be placed on the stack — this is faster and safer, as memory is automatically freed when the function exits.

If, on the other hand, an object "escapes" the function (for example, it is returned from it or stored in a global variable), then it must be placed on the heap to live longer than the function call.

Example in Go:

func foo() *int {
    x := 10
    return &x // x "escapes" the function, so it is allocated on the heap
}

Escape analysis helps optimize memory usage and improve program performance.
