Safia Abdalla: The Hitchhiker's Guide to All Things Memory in Javascript - JSConf Budapest 2016

Unlike C and other low-level programming languages, Javascript takes away the pain of memory management and garbage collection from the programmer. However, this doesn't mean that developers shouldn't be aware of the memory management and garbage collection implementation details of the Javascript programming language. Indeed, knowledge of both of those things can go a long way towards improving the performance of code.

This talk will take beginners through an exploration of Javascript's garbage collector and memory allocation implementations and their implications on how performant code should be written. Attendees will leave this talk having gained insights into the under-the-hood operations of Javascript and how they can leverage them to produce performant code.

Start at 3:20 to skip the technical difficulties.

Hello everyone watching! This video was the first iteration of the talk, if it was confusing to you in any way, considering checking out the version of it I did at CascadiaJS. It contains some minor improvements.

Great handling of the technical difficulties. I've been there and know how awkward that is :-)

Very interesting talk. I never cared about V8 memory management. Great talk thankyou soo much. Keep the great up

Uh my developer tools memory tab records different info... i am confused. It shows self size and total size not those 2 columns she mentions.

[adriannuske]

Very well delivered... sadly, no real information given, nor useful. Room for improvement.

I'm a little confused... she says there's a memory heap, but the graph shown is a DAG... a Heap is a type of Tree, and leaves in a Tree can't have multiple parents...
