问题 6. How does Node.js handle asynchronous code?

Node.js uses callbacks, Promises, and async/await to handle asynchronous operations. Callbacks are a common pattern, but Promises and async/await provide more readable and maintainable code.

Example:

fs.readFile('file.txt', 'utf8', (err, data) => { /* handle file content */ });

问题 10. Explain the difference between 'process.nextTick()' and 'setImmediate()' in Node.js.

'process.nextTick()' and 'setImmediate()' are used to execute a callback function in the next iteration of the event loop. 'process.nextTick()' has a higher priority and runs before 'setImmediate()'.

Example:

process.nextTick(() => { console.log('Next Tick'); });
