Node.js executes high-frequency asynchronous computing processes directly on local operational system machines instead of loading code instances strictly inside client applications.
Node works via a single thread running a continuous loop that hands computational file input-output tasks off directly to hidden system operating threads, handling thousands of API requests concurrently with minimal overhead.
const http = require('http');
const runtimeServer = http.createServer((request, response) => {
response.writeHead(200, {'Content-Type': 'text/plain'});
response.end('API Request Processed Successfully.\n');
});
runtimeServer.listen(3000, () => console.log('Server online.'));
