Go Compiler Internals: Escape Analysis, Stack vs Heap

Описание: Escape Analysis is one of the most misunderstood concepts in Golang.

In this video, you will learn how the Go compiler decides whether a variable goes on the stack or the heap, and why this decision has nothing to do with pointers alone — but everything to do with variable lifetime.

We cover:

What stack and heap really mean in Go

Why stack allocation is faster and GC-free

Why heap allocations need the garbage collector

How escape analysis works at compile time

Why returning pointers forces heap allocation

How function inlining changes escape decisions

Why escape analysis is about correctness first, performance second

This video explains escape analysis exactly how the Go compiler thinks, using simple mental models and real examples — no myths, no confusion.

If you want to understand Go memory management, compiler internals, and performance, this video is for you.

👉 Perfect for:

Go backend developers

System programmers

Engineers preparing for Go interviews

Developers transitioning from Node.js, Java, or C++
