This is because the event loop is paused for 1000ms and the setTimeout\nfires immediately after the event loop is no longer blocked (as more than 100ms have passed).\n\n## Install\n\n```sh\nnpm install\n```\n\n## Run tests\n\n```sh\nnpm test\n```\n\n## Support\n\nNode and Browser versions that support both `SharedArrayBuffer` and `Atomics` will have (virtually) zero CPU overhead sleep. \n\nFor Node, Atomic Sleep can provide zero CPU overhead sleep from Node 8 and up.\n\nFor browser support see https://caniuse.com/#feat=sharedarraybuffer and https://caniuse.com/#feat=mdn-javascript_builtins_atomics.\n\n\nFor older Node versions and olders browsers we fall back to blocking the event loop in a way that will cause a CPU spike. \n\n\n\n## Author\n\n👤 **David Mark Clements (@davidmarkclem)**\n\n* Twitter: [@davidmarkclem](https://twitter.com/davidmarkclem)\n* Github: [@davidmarkclements](https://github.com/davidmarkclements)\n","readmeFilename":"readme.md"}
