import{version}from'node-version';if(version.isAtLeast('20.0.0')){console.log('Running on Node.js 20 or newer');}if(version.is('22.0.0')){console.log('Running on exactly Node.js 22.0.0');}if(version.isAbove('20.0.0')){console.log('Running on Node.js strictly above 20.0.0');}if(version.isBelow('22.0.0')){console.log('Running on Node.js strictly below 22.0.0');}
