JavaScript Memory Leaks and How To Fix Them

Memory Management in JavaScript is often not a topic, but to avoid Memory Leaks in your web apps it's crucial to have a good understanding of how the Garbage Collector works, what can cause a Memory Leak, and how to analyze Memory Leaks with Chrome DevTools. In this video, I'm going to explain all of that.

Hello, with the setTimeout memory leak. Does no variable ever get garbage collected inside of setTimeout, or is it just references to dom elements that dont get cleaned up. If you had node set = to 10 would it still have been a memory leak?

Great explanation❤❤
Btw what is the tool u r using to draw and write ur explanation?

[salmanrana]

Hey bro! Awesome content. In your third approach you are deleting the property "delete nodes.btn". But "useStrict" doesn't allow us to use "delete". What can be other way to do that?

Amazing video❤ The fact that it has so less views and engagement makes me kinda sad

This pretty interesting, but when it comes to determine memory leaks in app like Angular, it very difficult to find it. Because it's huge amount of functions in it, and names like "lj, H9, Xv"... not sure what all those functions comes from.
Do you know how debug memory leaks in TypeScript apps? I believe it's after transpiler comes those names.
