Node.js is great for making server-side apps work faster, especially in full-stack development. But there are some challenges to keep in mind:

• Callback Hell: Node.js uses something called asynchronous programming. This can lead to many nested callbacks, which makes the code messy and hard to read.

  • Solution: Use Promises or async/await to make your code clearer and easier to follow.

• Single-threaded model: Node.js can handle multiple tasks at once without waiting, which is good. But, if your app does heavy math or processing, it can slow things down because everything runs on one thread.

  • Solution: Move tough tasks to other worker threads or even break them into smaller services.

• Memory Leakage: If data isn’t handled properly, it can cause your app to use more memory over time.

  • Solution: Check and monitor memory use often to find leaks early before they become a big problem.

Even with these challenges, Node.js is still a strong choice for full-stack development if you tackle these issues the right way.
