Notably, `SharedArrayBuffer` was disabled (starting Jan 5 2018) due to Spectre. Nevertheless, it is going to be re-enabled so it is worth reading up on shared memory in JavaScript -- more to the point, Atomics. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Atomics https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... I know a lot of people scoff at the Node/browser runtimes, which is warranted and totally unrelated to the language known as JavaScript, but performance is improving.

Is it disabled in the version of Chrome shipping with Electron? Considering they’re usually some number of versions behind, and this is a tool to make a desktop app, it would seem to be desirable to have it enabled regardless of Spectre since a desktop app can own your computer anyway if it wants. (It does make sense to have it disabled in a general purpose browser until mitigation’s are in place)
