If you have some complex computation you may need WebWorkers, in order to your main script may continue his work while heavy things are done in parallel.

Problem that Atomics solve is how WebVorkers can comunicate between each other (easy, fast and relaible). You can read about ArrayBuffer, SharedArrayBuffer, Atomics and how you can use them for your benifits here.

You shouldn't bother about it if:

• You are creating something simple (e.g. shop, forum etc)

You may need it if:

• You want to create something complex, memory consuming (e.g figma or google drive)
• You need that if you are looking to work with WebAssembly or webgl and you want to optimize performance
• Also you may need it if you want to create some complex Node.js module
• Or if you are creating complex app via Electron like Skype or Discord
