Can you make JavaScript run even faster? Or is it limited as a single thread language?

In this video we talk a bit about JavaScript's mechanisms for concurrency and spreading the work out over multiple threads/cores. We'll cover the web worker API in a bit of detail, dedicated workers, and then we'll move on to creating a small testing setup. It's kind of interesting to explore the threading opportunities that JavaScripts offers through the Web Worker API, the various pitfalls and performance footguns that lurk there, and what you can do to mitigate these issues. We'll also explore using transferable objects with ArrayBuffer, and touch quickly on what SharedArrayBuffer unlocks in terms of concurrency and multiple threads reading/writing.
