Detect memory leaks like a pro. In this course, you will learn how to connect monitoring to your application, how to take memory snapshots and most importantly, how to compare them with each other to find leaks.

You will learn how memory is organized in V8, why short-lived objects are best, and how to write code that will help you find potential memory leaks.

You will learn how to write code that should not contain any leaks, how to find existing ones, and how to write memory-efficient applications.

The entire course is based on nodejs, but these rules can be used in any language that uses the garbage collector.

We will discuss the algorithms that the V8 uses, how long it takes to free memory.

We will also cover what is included in a memory snapshot, what is contaiment, summary, and how to work with comparing them to each other.

Effective and trouble-free operation of the application is work on many levels, thanks to this course one of them will be explained and I hope it will become a little more friendly at a time when conscious memory management has gone into the background, thanks to such a great tool as GC. However, he himself is not always able to fix everything, sometimes he needs a little help.

This is why this course was created.
I belive that together we can save a lot of memory!
