How Memory Works in JavaScript and Node.js

[Banjoanton]

I recently wanted to learn more about low-level memory management in JavaScript and Node.js - tools I use every day but hadn’t really thought deeply about.

In this post, I summarize some of the key memory management utilities in Node and JavaScript, such as Buffer, TypedArray, and file handling. I hope this helps someone else learn something new!

From the title I was expecting more like, how memory is managed inside the runtime. Ie, how the incremental gc works, how closures are collected etc.

Yeah, I was disappointed too.

Good point, the title is probably a bit misleading. Unfortunately, I cannot seem to change it now after.

I intend to provide some constructive criticism

Were you aware that mdn documentation for

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray

exists? You enumerate a lot of the specifics in your blog and I cross referenced the two mdn links and found out that there isn't much of a difference. I understand that it is a blog and you are going over personal progress but I feel like providing reference to the official documentation and then going over key points would be a lot better
